Product Detail

Supplying you with customized fire resistant rs485 databus cables, it is one of the reliable fire resistant rs485 databus cables manufacturers and suppliers, welcome to wholesale our products at good price from our factory.

Fire Resistant RS485 Databus Cables

Application:	The cables are designed for RS485 data connections where continued functionality is required during a fire situation. 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.
STANDARDS:	Basic design to EIA/TIA 485
VOLTAGE RATING:	60V
