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,Website:, interference free, data transmission where continued functionality is required during a fire situation.STANDARDS:Basic design to EIA/TIA 485VOLTAGE RATING:60VFIRE PERFORMANCECircuit IntegrityIEC 60331-23; BS 6387 CWZ; DIN VDE 0472-814(FE180); CEI 20-36/2-1; SS229-1; NBN C 30-004 (cat.
