An M8 4 Pin Female Cable is a type of circular connector cable that belongs to the M8 connector series (8 mm thread size). It is widely used in industrial automation, sensors, actuators, and robotics for transmitting signals or power.

Here’s a breakdown:

1. Connector Type

• M8 → Refers to the metric size (8 mm diameter thread).

• 4 Pin → Has four electrical contacts for carrying signals or low power.

• Female → The connector has sockets (holes) to accept the pins of a male connector.

2. Structure

• One end: M8 female circular connector (with 4 sockets).

• Other end: Often an M8 male connector, open wires, or other interfaces (like M12, RJ45, etc.), depending on the application.

• Cable: Shielded or unshielded, PVC, PUR, or TPE jacket depending on environment.

3. Applications

• Sensors & Actuators → For connecting proximity switches, photoelectric sensors, encoders.

• Industrial Automation → Signal transmission between machines and controllers (PLC, I/O modules).

• Robotics → Data and small power supply to robotic components.

• Measurement & Control Systems → For compact devices needing reliable, vibration-resistant connections.

4. Key Features

• Compact size for tight spaces.

• Threaded coupling ensures secure, vibration-proof connection.

• Rated for IP65/IP67 (dustproof and waterproof) in most industrial versions.

• Carries low-voltage signals or small amounts of power (typically 60–250 V, 1–4 A depending on design).

✅ Example: An M8 4 Pin Female Cable to Open End is often used to wire a sensor directly into a control cabinet.
