  • 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.
  • For highly flexible applications (power chains, moving machine parts)
  • High oil-resistance

Application range

  • Communication at sensor/actuator level
  • Sensor-/actuator wiring

Product features

  • PUR versions are halogen-free according to IEC 60754-1
  • Flame-retardant according to IEC 60332-1-2, UL FT-2 flame test
  • 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).
