UNITRONIC® Li2YCYv (TP)
Shielded data cable with PE core insulation, reinforced outer sheath and twisted in pairs
UNITRONIC® Li2YCYv (TP) – shielded PVC data cable in twisted pairs, with black, reinforced sheath suitable for outdoor installation
Cables for RS485/RS422
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
