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
