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.

Key Features

  • 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.

Typical Applications

  • 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
