FRNC PROFIBUS cable UL/CSA certified

Bus cable for PROFIBUS-DP, -FMS and FIP. UL/CSA-approved, halogen free, enhanced flame retardance, oil resistance. Temperature range from -30°C bis +80°C

FRNC = Flame Retardant Non Corrosive
- Reduction of flame-propagation and
density and toxicity of smoke gases
in the event of fire
- Minimisation of damage to buildings
and production facilities
- Safety for staff and in
areas with high density of people

  • Cables can be used for PROFIBUS-DP as well as PROFIBUS-FMS and FIP
  • For use where the combination of a halogen-free outer sheath with properties similar to PUR and enhanced flame-retardance is required
  • Fast Connect (FC) cable design

Application range

  • This cable provides special advantages for use in sensitive areas where fire propagation must be avoided and the presence of toxic fumes would cause personal injury and damage to equipment.

Product features

  • Halogen-free
  • Vertical Tray Flame Test according to UL 1685
  • Oil-resistant
  • Based on the bit rates listed, in accordance with PNO specifications the following maximum cable lengths for a bus segment apply
    (cable type A, PROFIBUS-DP):
    93.75 kbit/s = 1200 m
    187.5 kbit/s = 1000 m
    500 kbit/s = 400 m
    1.5 Mbit/s = 200 m
    12.0 Mbit/s = 100 m
