ZION COMMUNICATION’s RS485 Armored Cable Series is engineered for mission-critical industrial environments requiring strong mechanical protection, superior EMI resistance, flame safety, and long-distance stable RS485/RS422 serial communication.
This series combines:
24AWG stranded tinned copper conductors
Foam PE insulation for low capacitance
Double shielding: Aluminum Foil + Tinned Copper Braid
Steel Wire Braid (SWB) armor for mechanical strength, rodent resistance and crush protection
LSZH (Low Smoke Zero Halogen) inner & outer jackets for enhanced fire performance
Ideal for railway signaling, tunnels, BMS fire systems, industrial automation, oil & gas, heavy machinery areas, and environments with high mechanical stress or EMI interference.
Armoured Construction (SWB): Strong mechanical protection against impact, crushing, and rodents.
Double Shielding (Foil + Braid): Superior EMI/RFI suppression for industrial communication.
24AWG stranded tinned copper conductors ensure low attenuation and stable signal integrity.
LSZH Inner + Outer Jacket: Low smoke, halogen-free, suitable for public buildings, tunnels, transport hubs.
120Ω characteristic impedance, optimized for RS485/RS422 multi-drop networks.
Low capacitance FPE insulation supports long-distance serial communication.
Ideal for high-risk or harsh environments where standard RS485 cables are insufficient.
RS485 / RS422 serial bus communication
Industrial automation & PLC networks
Tunnels, subway systems, railway signaling
BMS fire protection, alarm & monitoring systems
High-EMI factory environments with motors/VFDs
Outdoor or semi-outdoor communication
Access control & security communication lines
Heavy machinery / power plant automation
