An M12 5-pin cable is commonly used in industrial and automation applications for transmitting power, data, or signals in a compact, robust form. The "M12" refers to the 12mm metric thread on the connector, and 5 pins means it has 5 separate conductors for carrying different electrical signals or voltages.

Common Applications of M12 5-Pin Cables:

  1. Sensors and Actuators:

    • Used to connect proximity sensors, encoders, photoelectric sensors, etc., to control systems like PLCs.

    • The 5 pins can be used for power (e.g., 24V and GND) and signal lines (e.g., analog output, digital I/O, or communication lines).

  2. Industrial Ethernet and Fieldbus Communication:

    • Some 5-pin versions are used for CANopen, DeviceNet, or Profibus communication protocols.

    • Shielded versions may support data transmission with higher resistance to EMI.

  3. Power Distribution:

    • Can be used in low-power distribution for field devices, often in 24V DC systems.

  4. LED Lighting and Indicators:

    • In smart lighting systems within machines or production lines.

  5. Robotics and Motion Control:

    • Connecting servo drives, stepper motors, or feedback devices.

  6. Safety Systems:

    • Interfacing safety sensors or emergency stop buttons where multiple connections are needed.

Pinout Example (Generic for Sensor Use):

Pin 1 – +24V (Power)
Pin 2 – Digital Output 1 or Signal
Pin 3 – 0V (Ground)
Pin 4 – Digital Output 2 or Signal
Pin 5 – Shield or Communication line

Note: Always check the specific pinout and wiring diagram provided by your equipment manufacturer—configurations vary between applications and vendors.
