AS-INTERFACE cables for networking systems in the field

  • Communication at sensor/actuator level.
  • Halogen free (rubber), UL-approval (PVC), oil resistant (TPE).
  • Temperature range from -40°C bis +90°C

"LD” = Long Distance

Product Features

  • Conductor: fine-wire tinned-copper strands
  • Core insulation: blue and brown
  • Outer sheath:
    • rubber (G), halogenfree
    • thermoplastic elastomers (TPE)
    • PVC
  • Outer sheath: yellow (RAL 1023), black (RAL 9005), red (RAL 3000)

  • Data and power are transmitted via an unscreened, geometrically coded two-core flat cable (protection against polarity reversal).
  • The conductor is contacted by "piercing technology" within the ASI modules.
  • The sensors are connected to the ASI modules (coupling modules) using round cables (connection cables).


  • The new BUS ASI LD 2 x 2.5 (Long Distance) allows even modules located further away to be connected.
  • AS-I power supplies can be reduced. The BUS ASI LD is downwards-compatible with version 1.5.
  • The rubber versions are halogen-free

  • ASI is standardized Europe-wide in EN 50295 and internationally in IEC 62026-2.
  • PVC A version with UL/CSA (CMX) certification
  • UL/CSA version: CMG c(UL)us or (UL)CL2 or AWM 300V FT4 certified
