Li2YCYv (TP)
is a data cable with low capacitance for wiring of data systems at transmission rates up to
10 Mbit/s and is qualified for the serial interfaces RS422 und RS485. The cable can be used as a signal-, control- and
measuring cable as well as for transmission of low, sensitive signals and high bit rates.
Decoupling by means of twisted pair cable design and the screen protects against electromagnetic interferences.
The cable with reinforced outer sheath is designed for fixed installation indoors and outdoors as well as for laying
directly in the ground. The cable can be used for solderless connections, e.g. connections with insulation displacement
technology and Maxi-Termi-Point wiring.
