Benefits

  • 7-wire braided conductor (UNITRONIC® Li2YCY (TP) and UNITRONIC® Li2YCYv (TP)) can be used for Maxi TERMI-POINT® wiring
  • Overall shield minimises electrical
    interference
  • Decoupling of circuits by means of
    twisted-pair (TP) design (crosstalk effects)

Application range

  • Particularly suitable for wiring data systems with transmission rates up to 10 megabits per second, and is suitable for the RS422 and RS485 interfaces.
  • For fixed and limited flexible installation
  • Can be used in dry or damp rooms
  • Signal, control and measuring cable, for transmission of weak, sensitive signals and high bit rates
  • UNITRONIC®
    Li2YCYv (TP) with its reinforced, nominal/ minimum average wall thickness of at least 1.8 mm of the black outer sheath (Yv) is designed for indoor and outdoor use as well as for applications where a reinforced outer sheath may turn out to be advantageous
