Product Description

RS485/RS232 Multi-Pair Communication Cable (28AWG, 4–12.5 Pairs, Foil Shield, PVC, 120Ω)

Stable, Low-Capacitance Data Cable for Industrial Automation & Serial Communication

Available Models: 73004 (4 pairs) · 73005 (5 pairs) · 73006 (8 pairs) · 73012 (12.5 pairs)

ZION COMMUNICATION RS485/RS232 multi-pair cables are engineered for reliable, low-noise and interference-resistant data transmission in industrial control, building automation, instrumentation, and serial communication systems.
All cables feature 28AWG stranded tinned copper conductors, Foam PE insulation, 100% foil shielding, and a durable PVC jacket, achieving 120Ω characteristic impedance and low capacitance for stable high-speed differential signaling.

Key Features

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

  • Foam PE (FPE) insulation reduces capacitance and enhances high-frequency performance.

  • Overall aluminum/polyester foil shield (Beldfoil® type) provides excellent EMI/RFI protection.

  • Tinned copper drain wire enables reliable grounding and shield termination.

  • 120Ω characteristic impedance, ideal for RS485/RS422/RS232 communication systems.

  • Low capacitance:

    • 11 pF/ft (36 pF/m) cond-to-cond

    • 20 pF/ft (66 pF/m) cond-to-shield

  • Voltage rating: 150 V (CL2), 30 V (UL AWM 2919).

  • Operating temperature: −20 °C to +60 °C.

  • Available in 4 to 12.5 pairs to match different wiring densities.

 Typical Applications

  • RS485 / RS422 / RS232 serial data transmission

  • PLC, DCS and factory automation networks

  • Industrial motion control and monitoring

  • Building management systems (BMS), HVAC networks

  • Security, access control and alarm systems

  • Instrumentation, sensors and remote I/O links
