Industrial Cables

Li2YCY PiMF

Application and Description

Li2YCY PiMF is particularly suitable for wiring data systems and controls in large industrial plants, for the transmission of sensitive signals and high bit rates for enhanced requirements in near-end cross-talk attenuation and high electrical interference in the circuits. For measurement value transmission and serial 2-wire interfaces, Cables of this type are intended for limited flexible use, and for fixed installation in dry and damp interiors.

Standard and Approval

CE Low Voltage Directive 73/23/EEC and 93/68/EEC, ROHS compliant
