■RS485/RS232 Industrial Communication Cable Series

28AWG • 2–25 Pairs • Foil + Braid Shield • PVC Jacket • 120Ω

High-EMI Resistant Multi-Pair Data Cables for Industrial Automation & Serial Communication

Available Models:
73102 (2PR) · 73103 (3PR) · 73104 (4PR) · 73105 (5PR) · 73106 (8PR) · 73112 (12.5PR) · 73118 (18PR) · 73125 (25PR)

ZION COMMUNICATION’s RS485/RS232 Foil+Braid Shield Series is engineered for industrial-grade data transmission, offering excellent EMI/RFI protection, low signal loss, and high reliability in harsh electrical environments.
Using 28AWG stranded tinned copper conductors, Foam PE insulation, and double shielding (Aluminum Foil + Tinned Copper Braid), this series delivers 120Ω impedance, low capacitance, and stable differential signaling for RS485/RS422/RS232 communication systems.

■Key Features

  • Double Shielded Structure:
    Aluminum Foil (100% coverage) + Tinned Copper Braid → superior EMI resistance, ideal for heavy industrial sites.

  • 28AWG stranded tinned copper conductors ensure flexibility and strong signal integrity.

  • Foam PE insulation provides low capacitance for long-distance, high-speed communication.

  • 120Ω characteristic impedance optimized for RS485/RS422/RS232 protocols.

  • Excellent crosstalk suppression for multi-pair high-density installations.

  • Durable PVC jacket, flame-retardant and suitable for indoor industrial environments.

  • Wide model range: 2–25 pairs for flexible system design.

  • Operating temperature: –20°C ~ +60°C.

  • Ideal for environments with motors, VFDs, inverters, relays, and switching power supplies.

■Typical Applications

  • RS485 / RS232 serial data transmission

  • PLC & DCS communication networks

  • Industrial automation and motion control

  • Factory instrumentation and monitoring systems

  • BMS / HVAC / Smart Building communication

  • Access control, security, alarm systems

  • Long-distance multi-pair control/monitoring cables

  • EMI-sensitive or electrically noisy industrial environments
