Firetox Flame Retardant Cables
LSZH Flame Retardant RS 485 Databus Cables
APPLICATION
LSZH Flame Retardant RS 485 Databus 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
