What Is an M8 4-Pin Cable?

An M8 connector has an 8 mm diameter thread. The 4-pin version includes four electrical contacts, typically used for low-power signal and control applications in industrial systems.

Common Applications

1. Sensor Connections

  • Connects proximity sensors, photoelectric sensors, temperature sensors, and position encoders

  • Transmits digital (PNP/NPN) or analog (e.g., 0–10V, 4–20mA) signals to control systems

2. Actuator Control

  • Powers and controls small actuators, such as solenoid valves or mini motors

  • Supports basic signal and power transmission

3. IO-Link Devices

  • Frequently used for IO-Link communication, enabling bi-directional data exchange between smart sensors and controllers

4. Robotics & Compact Machinery

  • Ideal for space-constrained environments like robotic arms or compact automation cells

  • Offers secure, vibration-resistant connections

5. Industrial Vision Systems

  • Interfaces with LED lighting, triggers, and position sensors in machine vision setups
