EIB-BUS (KNX) Cables

EIB-BUS cable is a shielded, twisted-pair communication cable made for the data bus that connects devices to each other in the KNX building automation system, the successor of EIB. In residential, hotel and office buildings, it carries both data and bus power between the sensors and actuators of lighting, blind and HVAC automation. In this category, halogen-free (LSZH) sheathed types from manufacturers such as Reçber, Erse and Mekas, in 1x2x0.8 mm and 2x2x0.8 mm configurations, are sold by the meter. Choose the number of pairs according to the need for a spare pair, and the sheath material and reaction-to-fire class according to the requirement of the building project; verify KNX compatibility from manufacturer data. In the two-pair configuration, the first pair is used for the bus line and the second pair is reserved as a spare or for auxiliary supply. Designed for the KNX line, this cable does not replace a Profibus or Profinet cable, which have a different impedance and core configuration.

How to choose EIB-BUS Cables

EIB-BUS cable is a shielded, twisted-pair communication cable made for the data bus that connects devices to each other in the KNX building automation system, the successor of EIB. In residential, hotel and office buildings, it carries both data and bus power between the sensors and actuators of lighting, blind and HVAC automation.

  • Clarify the circuit duty first: power distribution, control, fire safety, Ethernet or analog signal.
  • Compare conductor cross-section, core count, insulation and shielding against the installation route.
  • Switch to the proper cable family early when flex duty, oil resistance, halogen-free jacket or fire integrity is required.
