  • Overall shield minimises electrical
  • Individually shielded cores minimise crosstalk between cables routed in parallel

Application range

  • When a lossless transmission of data has to be guaranteed in fields with strong interference, cables with individually-screened cores and an additional overall screening are used
  • Dry or damp rooms

Product features

  • Wire-screen can be used as outer conductor
  • The cable remains flexible despite multiple screening
  • Flame-retardant according to IEC 60332-1-2

Norm references / approvals

  • Based on VDE 0812


  • Finely stranded bare copper wires
  • Core insulation made of PVC
  • Tinned-copper braiding for each core
  • Inner sheath made of PVC over each shielded core
  • Tinned-copper braiding
  • Outer sheath made of PVC
    Outer sheath colour: pebble grey (RAL 7032)
