Application

Appliance and data transmission cables RD-Y(St)Y are used in measuring and control technology, for example in control centers of industrial lines and power plants. The static screen protects the transmission circuits against outer electrical intreferences. Pairs are twisted with short pitches and different lenghts that leads to good crosstalk attenuation values in a bunch. Cables are designed for transmission of analog and digital signals up to frequencies of approx. 10 kHz. These cables offer advantages of fast and economic installation. This solderless conecting technique is based on a compression termination that uses a spring-clip for the connection of the cable to a square rigid post withot pre-stripping. For this technique it is necessary to have an exact 7-core stranded PVC conductor and a semi-rigid PVC.

Note:

  • CE = the product is conformed with the EC Low-Voltage Directive 2014/35/EU.
  • Halogen-free type RD-H(St)H available on request, see section.
  • Conforms to RoHS.
