Room temperature controller - When building a new house or renovating, you have numerous interesting options for organizing the control of the room temperature. We will tell you how you can use various bus systems such as KNX, radio or LCN in addition to the conventional temperature setting. Automation not only increases living comfort, but also contributes to the value of your building. This enables you to make necessary adjustments or changes even when you are not at home. This eibabo® catalog provides room temperature controllers for all common applications.What are KNX room temperature controllers?KNX room temperature controllers are part of a building's heating system. These are used for individual room temperature control of interior rooms and have various measuring ranges. The respective devices can differ significantly in terms of application and the functions provided for operation and comfort. For example, the differences are whether static heating surfaces or underfloor heating are to be controlled or whether air conditioning and ventilation functions are to be provided.Do not confuseThermostats are also known as room temperature controllers. Installed on radiators, however, they measure the temperature at the heating and usually only differentiate between on and off.KNX room temperature controllers, on the other hand, continuously control between 0 and 100 percent and use a heating actuator to communicate with the heating actuators.How is the room temperature controlled using KNX?A KNX room temperature controller determines the control difference between the target temperature and the actual temperature. The calculated control difference is sent as a 1-byte command value telegram (a value between 0 and 100 percent) via the KNX bus to the corresponding channel of a heating actuator. This processes the signal and then controls the actuator.The following small example illustrates the rough functionality. The actual manufacturer specific control algorithm may be different:The room temperature controller determines a current temperature of 18 degrees Celsius (controlled variable). However, the desired room temperature should be 22 degrees Celsius. The 22 degrees Celsius then represents the setpoint for the controlled variable. The resulting difference between the actual value and the setpoint is the control deviation. The control difference is 4 degrees Celsius and is used to determine the control variable that is to be used to influence the room temperature. Assuming the manipulated variable is 25%. This value is transmitted as a 1-byte telegram (0-255 = 0-100%) from the room temperature controller to the heating actuator. In this case 63.75. For example, the actuator takes 2 minutes to fully open. The time required for the respective actuator to open or close can be found in the data sheet for the thermoelectric actuator. This information must have been previously stored in the parameters of the actuator using Engineering Tool Software (ETS). With a command value specification of 25%, the actuator would switch on the actuator for 30 seconds (this corresponds to 25% of 2 minutes) and switch it off for 90 seconds. The actuator then switches on again for 30 seconds and so on. If the room temperature controller calculates and transmits a different command value specification, the switching cycle for the actuator also changes.Image: Gira 210003 KNX continuous controllerWhat is the difference between KNX continuous controllers, KNX object controllers and KNX room temperature controllers?The selection of KNX temperature controllers is very large. eibabo® offers products from all leading manufacturers of control technology for HVAC (heating, air conditioning, ventilation) in smart home automation. These include ABB, Berker, Busch-Jaeger, Eaton, Elsner Elektronik, Eltako, EIBMARKT, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens, Theben and Thermokon. Many of these manufacturers use different designations, such as KNX continuous controller, KNX object controller or KNX room temperature controller.KNX room temperature controllers continuously record temperature values and forward them to other system components as KNX signals that can be evaluated. This process takes place continuously. A KNX continuous controller is therefore the same as a KNX room temperature controller. The situation is different with a KNX object controller. Object controllers are room temperature controllers without direct adjustment options on the device for the setpoint temperature. Object controllers were developed for object use. In public objects, as a rule, direct adjustment by strangers should be prevented. The values are parameterised directly via the ETS (software). You can change these directly via KNX (KNX buttons, KNX operating panels, KNX visualisations) in the setpoints. KNX object controllers are often cheaper and suitable in private areas for corridors, basements or storage rooms.What do you have to consider when positioning a KNX room temperature controller?As a rule, the installation is carried out using a branch switch box with 4 screw bosses, one switch box deep. Alternatively, use an electronics box if a separate bus coupler is required. With our convenient search function, you can quickly find the right items here in the eibabo® technology store. TIP:There are multi-channel KNX room temperature controllers for installation in your electrical distribution. Here, the temperature is measured via separate KNX sensors, for example from KNX buttons or KNX motion detectors with an integrated temperature sensor. For optimal use of all functions and the best possible recording of the measurement data, please ensure that the installation height is 1.60 m from the top edge of the finished floor. In this way you ensure optimal control and user-friendly handling.How is a room temperature controller connected to the KNX bus?KNX room temperature controllers are equipped differently by the manufacturers. You can either buy the KNX room temperature controller including a bus coupler or you have to order the bus coupler separately. The required interface between the KNX bus and the KNX room temperature controller is called the bus coupler. You can tell whether your controller has a bus connection by the red and black bus terminal. The KNX controllers often offer included KNX binary inputs. These are used, for example, to integrate conventional buttons in the room to switch lights via KNX. These binary inputs usually correspond to the technical data of KNX push button interfaces and can therefore only be extended up to a maximum of 50cm.How important is the appearance of a KNX room temperature controller?There are controllers with or without a dial to adjust the temperature. Other models are operated via the display and menu controls. Everything is possible here. The controls should match your other switch range and reflect your modern, classic, simple or extravagant style of living. TIP:Don't just look at the exterior of a KNX room temperature controller, but also at its inner values. There are often considerable differences in the application developments (software) of the manufacturers. The possibilities that the respective software can offer you may be relevant to your project requirements. Think of:control behaviorInfluencing control processesOperating modes and external switching options or setpoint adjustment optionsstatus feedbacknumber of group addressesBehavior in the event of a bus voltage failureand much more What other properties should I consider before buying a KNX room temperature controller?In addition to the technical, optical and software properties mentioned, other factors can speak for or against a specific model.Do I need anti-theft or dismantling protection?What color or what material do I want for the control panel?Do the local conditions require wireless data transmission?Should it be regulated via a room controller?and some more What are room controllers with integrated KNX room temperature controller?An alternative to the KNX room temperature controllers presented here are the KNX room controllers, provided they have an integrated temperature controller. These are devices that you can use to centrally control lighting, temperature and blinds, for example. Such controllers can be used via individually assignable control panels for switching, dimming, regulating or controlling all required actuators and sensors. You can also get numerous high-quality KNX room controllers here in the shop at top conditions. Use our intelligent search for your research.  Catalogue content:In this eibabo® catalogue Installation bus systems > Room temperature controller for bus system you will find items from the following product groups:Item overview:Building system technologyBus technologyButton interfaceClock thermostatContinuous controllerControllersEnd stripsEnergy efficientHeating controlHeating technologyHome controlHumidityMoellerfunkMoisture meterMultifunction displayNetworkingObject controllerRadio systemRadio transmitterRemote room sensorRoom controllerRoom sensorRoom temperature controllerRoom thermostatTemperatureTemperature controllerThermostatWireless temperature sensorfrom the following manufacturers:Manufacturer overview catalogue Room temperature controller:ABBAlre-itBerkerBusch JaegerEatonEberleElsnerElsoEltakoGiraHagerJungMDTMertenSiemensTheben
Dc power supply - Are you looking for a reliable DC power supply within your electrical installation? But you need more information to be able to decide on a specific device? In the following article we clarify frequently asked questions and support you in choosing the right device. At eibabo® we list a large number of switching devices for low voltage. This allows you to implement a DC power supply that can be used in electrical distribution installations in low-voltage networks.What is a DC power supply?Devices for the direct current supply supply the consumers connected to your electrical distribution system (fuse box or distribution cabinet) with low voltage. The scope of performance of the devices we offer ranges from under 5V to 12V, 24V, 48V to 54V.Good to knowWhen electric current flows, charge carriers move. If the voltage has the same polarity continuously, the direction of movement of electrons and protons is also constant and it is direct current. If the polarity changes periodically, the direction of movement of the charge carriers also changes. Then there is alternating current.Most of the devices are mounted on the DIN rail in the control cabinet. In home automation and building technology, flush-mounted power supplies are also increasingly being used, which you can install directly in flush-mounted boxes (deep switch boxes). Discover a large selection of high-quality DC power supply products with us. These include, for exampleDC/DC converterCompact power supplies, power supplies and power packsSwitching power supplies and switching power supplies (for mounting on DIN rails, for surface mounting, for flush mounting and for fixed installations)as well as primary switching regulators, transformer rectifiers and wide-range switching power supplies What are DC/DC converters?DC/DC converters are used wherever one direct voltage has to be converted into another. In other words, DC/DC converters convert the power of a direct current (DC) source from one voltage level to another. In this case, the input energy is temporarily stored and then delivered to the output with a different voltage. The output voltage can be either higher or lower than the input voltage. Electrical energy is stored either in magnetic field storage components (such as a transformer) or in electric field storage components (such as a capacitor). The devices will not work with AC power sources. Good to know:The devices for direct current supply are characterized by a very favorable price-performance ratio and a high level of efficiency. Considering efficiency is important because there are power losses when converting between different voltage levels. Depending on the voltage, current and type of DC/DC converter, the efficiency varies from 75% to 95% or more.What are DC power supplies?In contrast to DC/DC converters, DC power supplies are supplied with AC voltage and provide a specific DC output voltage. The devices are available with different performance data, among other things in order to meet the sometimes different mains voltages in many regions of the world. On the other hand, the various electronic components in an installation require different voltages to achieve their highest efficiency values. In addition to direct current power supplies, which supply a fixed constant voltage, you will also find power supplies with dual outputs or multiple outputs at eibabo. Each output can have a different constant voltage. You are thus able to supply several loads with different operating voltages from one power pack.Power supply or power supply?A power supply is usually a compact device that usually supplies a fixed voltage. A power supply unit, on the other hand, is more complex and expensive. This means that several voltages can often be set variably.In Europe, 12V and 24V power supplies are the most common. Our range of products covers the power range from below 5V to 54V. The spectrum ranges from small, narrow, efficient power supplies to very powerful DC power supplies, converters and complex power supplies.What is the difference between a transformer, a transformer rectifier and a switching power supply?A transformer is a component consisting of coils, copper wire and an iron core. Typically, a transformer increases or decreases electrical voltages. Incoming AC voltage is converted into outgoing AC voltage in a certain ratio. The device does not transform AC voltage into DC voltage. A transformer always uses AC voltage, while a power supply unit uses DC voltage.A transformer rectifier is something like the predecessor of the switching power supply and is only used occasionally today. The device generates DC voltage from AC voltage. With an internal transformer, this device also increases or decreases incoming AC power. The AC voltage is rectified by means of a bridge circuit and then smoothed by a capacitor. A built-in linear regulator on some models ensures that the output voltage is kept at a constant level. These devices are called regulated power supplies, while models without a linear regulator are called unregulated power supplies. A capacitor for short-term damping of voltage peaks is also not installed in all models. The direct current can be taken from the device output. A major disadvantage of these devices is the relatively high permanent power consumption, even when no consumer is connected.The switching power supply is the further development of the transformer rectifier. Here, too, an AC voltage is converted into a larger or smaller AC voltage by a transformer. For safety reasons, the primary circuit (e.g. with 230V mains voltage) is galvanically isolated from the secondary circuit (e.g. with 12V). A bridge rectifier now generates the required direct current, which is also smoothed here by a capacitor.Image: Eltako SNT12-230V/24VDC-1A switching power supplyWhat are wide range power supplies?Power supplies with a 'wide range' on the input side can be operated with different nominal voltages. These devices do not have to be adjusted manually or automatically to the nominal voltage applied.Which devices for DC power supply are recommended?When purchasing a DC power supply, make sure the device meets your requirements for the intended use. Recommended devices for DC power supply are characterized by:a high quality finisha very good efficiencya high energy efficiency You will find the information on efficiency and all other technical specifications in the data sheets as well as in the product description of the respective devices. Here in the shop you only get devices from top manufacturers. These include Eaton, Eltako, Jung, MDT, Phoenix, Omron, Merten, Siemens and many other well-known manufacturers.

Bulb socket - Of course, if you want to mount a new lamp, make sure that you use the right socket. There are, however, a large number of different versions, all of which have special or individual properties. Which socket you need can depend on the one hand on the amperage and on the other hand on the space available in the lamp. We will introduce you to the differences and similarities and support you in your purchase decision.Basically, the selection is huge and most of the differences are clear. Inexpensive plastic frames are available in the eibabo® shop as well as versions made of high-quality ceramic. You will also find models with different diameters and sockets into which the bulbs are screwed or clamped. Speaking of light sources: Last but not least, the choice of light bulb also determines which socket must be used. The counterpart to a socket is the so-called base of the light source. Proper functioning of the lamp can only be guaranteed if the base and socket fit together. TIPThe frames offered here are attached individually. Choose from models with screw holes, screw lugs, spring clamps, threads or mounting brackets. However, there are also distinguishing features, the purpose of which often only becomes clear at second glance. At this point we give you a small overview.Which lamp holders are the most common?The base is an indispensable element of any light source, since it performs the function of fastening and power connection. By connecting the base to the lamp socket, the lamp / illuminant is fixed to the light and supplied with energy. Of course, the lamp base and lamp socket must be of the same type, otherwise the connection will fail. Now one would think that this is self-evident and does not pose a problem in everyday life.Yes and no: Because the times when there were only lamp sockets with a thread are long gone. The modern world of lamps is now so diverse that the market for base types and the required lamp sockets has become very confusing. The manufacturers of modern lighting are constantly developing new variants. With a spontaneously bought lamp, you quickly acquire a surprise in the form of a previously unseen lamp socket. It's good if the first lamp is already there. But nothing lasts forever. Sooner or later it's time to replace a burned out lamp with a new one. We present the most common forms of lamp holders. Essentially, these are divided into screwable and pluggable sockets.E40 - screw socket for lamps with an output of more than 200 watts at 230 volts (use in the industrial sector or with conventional street lighting)E27 - classic standard screw socket for household lamps up to 60 watts at 230 volts with a plastic socket, up to 200 watts at 230 volts with a ceramic socket (usually used for Edison bulbs, energy-saving lamps, filament and LED)E14 - screw socket for lamps with an output of up to 60 watts at 230 volts (usually used for Edison light bulbs, energy-saving lamps, filament and LED)GU5.3 socket for simple plug-in pins with a spacing of 5.3 millimeters (often used in low-voltage spotlights with reflectors)GU10 sockets with bayonet lock, into which two solid pins are inserted, a quarter turn establishes the electrical connection (often used with spotlights with reflectors)G4 - receptacle for U-shaped plug pins with an average spacing of 4 millimeters (found in small halogen glass lamps or LEDs)G5 - Bayonet jack for fluorescent tubes with a pin spacing of 4.75 millimetersG13 - Bayonet jack for fluorescent tubes with a pin spacing of 12.7 millimetersG9 - receptacle for U-shaped plug pins with a mean distance of 9 millimeters (found in halogen glass lamps or LEDs) And that's by far not all. Here in the eibabo® shop you will also find sockets with the designations E10, R7s, 2G11, GX5.3, GZ10, G23 and around a dozen others.The 'E' in the screw sockets stands for Thomas Edison, the developer of the corresponding socket thread. The following number describes the diameter of the thread in millimeters. The 'G' is used for plug connections, with the following number indicating the mean distance between the two plug pins in millimeters.Image: Houben 102599 E27 lamp holderWhat material should I choose for lamp holders?When choosing a lamp holder, you often have a choice of different materials. You can choose from different metals such as aluminium, steel or brass, several plastics and ceramic/porcelain sockets.What is Bakelite?Bakelite is a thermoset phenol-formaldehyde resin that is easy to form during manufacture and has high resistance to electricity, heat and chemical attack. It was the world's first commercially successful plastic. It is rarely used today because once a product has hardened, it cannot be melted down and recycled.The main difference between these materials is their ability to withstand certain temperatures. For a rough estimate of which material is right for you, you can use the following information: modern plastic frames can withstand temperatures of up to around 210 °C, Bakelite is resistant up to 190 °C, ceramic frames and metal frames tolerate 230 °C and more. The higher the wattage rating on the bulb, the more heat is generated. For high heat output bulbs or special heat lamps, metal or ceramic sockets are usually the best option.How is the power connection to the lamp socket?Another difference is the type of cable connection. Here we distinguish between a detachable and a fixed connection. The fixed connection is usually made by soldering. In these cases, the lamp socket only has the contact pins required for this, to which the wires of the cables must be soldered. More often you get lamp sockets with detachable connections. These are made either via a screw connection or a plug-in connection / clamp connection.Whether you should opt for a lamp socket with a plug connection or a screw connection essentially depends on the type of cables you have. Modern lampholders offer special connection points, where the wires are fixed just by plugging them in with a spring mechanism. To loosen this connection, the tension on the spring is usually released with a pointed tool. This method of assembly is simple and quick. However, you need stable wire ends for this. You only have this for cables with solid conductors or when using ferrules. With flexible lines (finely stranded cores, strands) you cannot establish a secure connection in this way. If you have flexible cables, you should use sockets with screw connections. This method is a little more time consuming, but you'll attach the wires tightly and securely. Solid conductors can also be easily connected using the screw method.  Catalogue content:In this eibabo® catalogue Accessories for lighting > Lamp holder you will find items from the following product groups:Item overview:Adapter socketAluminum frameBuilt-up versionBulb socketCeiling mountConnection lineConstruction versionFestoon holderHanging versionIllumination plugInstallation setJunction boxLamp baseLamp holderLamp socketLighting holderMiniature versionPendulum socketPlastic framePorcelain settingRecessed socketRubber plugScrew socketSealing ringSmall versionSocketSocket adapterThrough socketfrom the following manufacturers:Manufacturer overview catalogue Bulb socket:BachmannBJBBrumbergEVNHoubenIDVKleinhuisPaulmannRenzScharnberger+Has.SchuchSignify LampenSLV
Flexible electric cable - Did you know that there are different types of wiring in your house? Among other things, we distinguish electrical cables according to whether they have rigid or flexible core cables. Read here when which types are used and what you should consider when selecting flexible cables.How are flexible lines constructed?The conductive core of a flexible cable does not consist of a solid (monolithic) wire, but of many little wires twisted together. These little wires form an insulated core, the so-called stranded wire. Depending on the purpose of the product, several of these cores can be bundled together in a further sheath to form a cable. The most important selection criteria for such a product are:the number of insulated cores within the sheathing of a cable (this can be several dozen)the color and positioning of the cores within the sheathing of a cable (see twisted pair cable)the cross-section of the respective coresthe type and structure of the insulation and sheathing The number and cross-section of the cores determine the total power of the current that can be safely conducted. This is one of the most important features of a cable and is specified by the manufacturer at regular intervals on the outer insulation. We recommend using quality products from well-known manufacturers. Tolerances can occur with cheap no-name items, which usually have an adverse effect on the cross-section and thus impair the performance of the line. There are also differences in the shape of the wires or lines. Most often we encounter the round shape, but in some variants the outer shape can also be flat, for example. This affects the outer diameter and the possible uses.The type and structure of the insulation and sheathingInsulation appropriate for the application is the primary safety feature of an electrical cable. Their main task is:Protect people from contact with a live coreto protect the cable from mechanical damageto ensure a correct current flow without interference from the outsideto shield the environment from the influences of the line In a line, each core is separately insulated. This prevents contact between the electrical conductors in the cores and offers protection against mechanical damage. Another outer sheath holds all the components of the cable together and also protects the inner insulation from drying out, high humidity and other influences. Depending on the location and purpose of a line, different materials are used for the insulation. These should correspond to the expected mechanical, chemical and thermal influences. The UV radiation of the sun must also be taken into account. The following materials are therefore used most frequently in the area of classic household electrics:PVC ? inexpensive, flexible, low-wear, non-flammable and resistant to various chemical compounds, not suitable for high and very low temperaturesRubber - particularly flexible, suitable for medium to difficult operating conditions, resistant to low temperaturesPE - resistant to chemical compounds, pressure and low temperaturesSilicone ? particularly reliable at high temperatures up to around 200 °C, low mechanical strengthPUR ? high oil resistance and abrasion resistant immission and emissionCurrent-carrying cables generate magnetic fields. The immission protection protects the data flowing through the wire from external electromagnetic influences. The emission protection prevents the emission of electromagnetic interference signals through the line.The outer casing can consist of additional elements:Shielding made of metal foil or metal mesh as a barrier against immission and emission. These mainly include fault currents, radio waves, EM fields or radiation, which affect the transmission of signals in data lines.Armor as maximum line protection against mechanical damage.Cover made of (impregnated) cotton or silk to protect against mechanical damage, rot or for decorative purposes. Image: Various flexible linesWhat is the difference between flexible lines and rigid lines?Cables with rigid conductors are used for fixed installation in domestic installations. Cables with flexible conductors are used where you want to connect mobile consumers. Mobile consumers are, for example, floor lamps, coffee machines, radios or hair dryers. But why is that?Advantages and disadvantages of flexible, multi-core cables:high elasticity and flexibilitysmall power losseshigh quality circuitreliabilitypoor performance on HF networkshigh price In particular, the higher price and the more complex production of connections (e.g. due to the necessary cable lugs) stand in the way of the use of flexible cables for all areas of electrical installation. In comparison, solid conductors have the following advantages and disadvantages in these points:inexpensiveUse in HF networkseasier installationeasy connectionhigh rigidity, not very flexible, difficult handling You save money with solid conductors in fixed installation. However, the handling of rigid cables is too cumbersome for daily mobile use on electrical devices, extensions or distributors.Pliability of flexible linesThe number of cores and the diameter of the wires in a core determine the flexibility of the core of a cable. The standard DIN EN 60228 (VDE 0295) describes four classes of conductors: solid (i.e. single-core solid conductors), stranded, finely stranded and extra finely stranded. The thinner the wires, the easier it is to bend the line. TIPSingle-wire and multi-wire cables have different levels of flexibility. During operation, these should not be bent too much so that the core is not damaged. The rule of thumb for solid conductors is: The minimum bending radius should not be less than four to five times the diameter of the cable including the sheath. A line with an outer diameter of 11 mm should therefore not be bent below a radius of about 50 mm. Flexible cables are more flexible than solid cables. Their bending radius should not be less than three times the cable diameter.What is a stranded twisted pair?Information systems have become an integral part of life today. Telecommunications, the global Internet and television are part of our everyday lives. One of the most important components of such networks is the twisted pair line. This is a line consisting of four or eight copper wires. The cores of the twisted pair cables are offered as solid or in the form of stranded wires. The special thing about it is that the wires are twisted together in pairs. A shield increases the protection of the line against electromagnetic interference. Twisted pair cables are primarily intended for the transmission of digital information in Ethernet networks. twisted pair lines. The area of application is not only private houses and apartment buildings, but also commercial offices and industrial companies as well as public facilities such as schools and hospitals.What is the significance of the core colors in flexible cables?If you look at a typical flexible power supply cable, you will see strands of different colors in it. In Germany these are typically black, brown, blue, gray and green-yellow. In order to be able to use the individual wires correctly, you should know the meaning of the color coding. This is important so that other people can rely on the correct assignment of the colors during repairs, checks or changes. Installers derive the function of individual wires from this. Instructions are printed on the sheathing, which provide information about the number of wires and their diameter. The following rules apply to the colors of the wires in Germany and the EU: The basic colors are brown, blue and green-yellow. There are also the extended basic colors black and grey. Alternative colors are white, orange, red and purple.NoticeDepending on the manufacturer, country and type of cable, there are major deviations in the colors of the core insulation. Please use the standard applicable in your country.The following applies to Germany and large parts of Europe: the brown wire is phase 'L1' and is always used as the current-carrying line to the device. The blue wire is the 'N' neutral and carries the power back to the source. The green-yellow wire is intended for grounding. This is called the protective conductor 'PE'. The extended basic colors black and gray are used when it is a three-phase AC installation. The black wire represents phase 'L2', the gray wire represents phase 'L3'. The alternative colors of white, orange, red and purple are intended to complement certain installations.Which cross-section do I have to pay attention to with flexible cables?Flexible cables with stranded copper for normal household use start with a standard cross-section of 0.5 mm². The dimensions 0.75 mm², 1.5 mm² and 2.5 mm² are widespread. The cross-section you need depends on numerous conditions. These include:the type of current (direct current, alternating current)the level of the operating voltagethe amperagethe length of the linethe type of transferthe voltage dropthe phase angle These parameters result in a formula that can be used to calculate a cable cross-section. Due to the many variables, for safety reasons we do not give any general recommendations for the use of certain cross-sections at this point.Simply browse through our large eibabo® range. Here you will find flexible PVC hose lines, silicone lines, rubber lines or PUR lines at particularly reasonable prices.  Catalogue content:In this eibabo® catalogue Cables > Power cable < 1 kV, for moving application you will find items from the following product groups:Item overview:Control cableControl lineData cableData lineDevice connection cableExternal lineFuse boxHigh voltage cableHouse connection cableInsulating tubeLine jumperMachine control lineMeasurement lineMeasuring systemMedium voltage cableOvervoltage protectionPower cablePower control linePower lineRubber cableRubber hose lineServo lineSilicone cableSilicone lineSupply cableTrailing cableTrunk cable ringVoltage tapfrom the following manufacturers:Manufacturer overview catalogue Flexible electric cable:BachmannBarthelmeComelit GroupDiverseEatonElsproFaber KabelGlenHagerHartingHelukabelIgusLappkabelLeoni StuderLützeMurrelektronikPhoenixPilzScharnberger+Has.WaltherWaremaWeidmüllerWieland
