BMS (Building Management System) RS485 Data Cable RE-02Y(St)H 1P18A

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

Airport ULV Cables    

Applications

The cables are designed for RS485 data connections. This 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.
