Fire Resistant Signal & Data Cable

Fire Resistant RS485 Databus Cables

APPLICATION

The 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.

STANDARDS

Basic design to EIA/TIA 485
