描述

This 4-core shielded industrial signal cable is engineered for low-voltage signal transmission in industrial automation, process control, building automation and machine wiring environments. It is commonly used to connect sensors, PLC modules, transmitters, control panels, proximity switches, pressure sensors, temperature sensors and other industrial devices that require stable analog or digital signal transmission.

The cable consists of four insulated conductors with color-coded identification, making field wiring and terminal maintenance easier. The overall shielding structure combines aluminum foil shielding and copper braid shielding, providing both high-frequency and low-frequency interference suppression. This double-shielded design helps reduce signal distortion caused by frequency converters, motors, power cables and other electromagnetic noise sources in industrial sites.

Constructed with high-purity tinned copper conductors, the cable offers low resistance, stable signal transmission and good oxidation resistance. The outer jacket is made of flame-retardant PVC or PUR material, providing mechanical protection, oil resistance, abrasion resistance and flexibility for installation in cable ducts, control cabinets and moving machine parts.

It is widely used for 4-20mA analog signal circuits, RS485 communication wiring, sensor signal lines, PLC input/output wiring, temperature transmitter connections and industrial control panel wiring. The cable supports both fixed installation and occasional flexing applications, making it suitable for industrial automation system integrators, machine builders and control cabinet manufacturers.

Standard AWG options include 24AWG, 22AWG and 20AWG, with standard lengths of 100m/roll or custom cut lengths. We also support custom conductor cross-section, jacket material, shielding structure, color code and private-label packaging for bulk OEM orders.
