Fire Resistant RS485 Databus Cables

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
