Application
UNITRONIC Li2YCY (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 is designed for fixed installation in dry and damp interiors and for conditional flexible use. The cable can be used
for solderless connections, e.g. connections with insulation displacement technology and Maxi-Termi-Point wiring.
