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.
