Fire Resistant RS485 Databus Cables

Application

Fire Resistant RS485 Databus 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.
