RS485 Data Cable RE-02Y(St)H 1P18A

RE-02Y(St)H 1P18A (CU/PE/OSCR/LSZH 1×2×18AWG)

Airprot cables are designed for RS485 data connections. Airprot cable combines low capacitance insulation with

one of the highest levels of screening to provide high speed, interference free, data transmission where

continued functionality is required during a fire situation.
