EIB/KNX BUS 75 Ω - building automation


As a buscable for EIB/KNX systems, in the field of intelligent building automation (e.g. motion detectors, lighting, heating / air conditioning / ventilation, time recording systems, blinds, etc.) as well as measuring and control cable in power installations. Suitable for fixed installation on and under plaster and in pipes and cable ducts, in dry, damp and wet rooms but not outdoors without UV protection. Standard acc.to KNX-Spec.: EN 50090-2-1 & EN 50090-2-2

Special Features

  • TKD EIB/KNX cables are testet with increased testing voltage (4 kV)
    The cables can be layed without restrictions next powercables or touch them.
  • YCYM - standard description in Germany for so-called EIB/KNX cable with
    high voltage test 4kV and corresponds to our type: EIB/KNX BUS (St)-PVC
  • EMC compliant shielding


  • conform to RoHS // LABS-/silicone-free (during production)
  • conform to 2014/35/EU-Guideline ("Low-Voltage Directive") CE
  • FRNC: Flame Retardant Non Corrosive, halogenfrei
  • EIB/KNX - the KNX system was originally called "European Installation Bus"
                      (abbreviated EIB)
