Firetox Flame Retardant Cables
LSZH Flame Retardant RS 485 Databus Cables
APPLICATION
The cables are designed for RS 485 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 adapted to EIA/TIA 485
