Cable port dimensions on the distribution box

Distribution boxes typically use M8, M12, or M16 ports, with port diameters standardized according to IEC 61076-2-1xx specifications. Port Types and DimensionsM8 Ports: Commonly used for sensor and actuator connections, available in 4, 6, or 8-port configurations. The M8 designation refers to the 8 mm thread diameter of the connector.

M12 Ports: Often used for higher current or data connections, available in 4 or 8-port configurations. The M12 designation indicates a 12 mm thread diameter. M16 Home Run Connector: Used for main cable entry, with a 16 mm thread diameter, providing a centralized connection point for multiple outputs.

Cable Lengths and Pre-WiringStandard pre-wired cable lengths for M8 and M12 ports are 1 m, 2 m, 3 m, 4 m, 5 m, and 10 m. Custom lengths may be available upon request.

High-bending PU

R cables are available for applications with constant movement, ensuring durability and flexibility.

Additional Features

Coding Options: A-coded, B-coded, or other IEC-compliant coding prevents incorrect mating of connectors.

I

P Rating: Most distribution boxes are rated IP67, providing dust-tight and water-resistant protection. Labeling and Customization: Ports can be labeled for power, data, or ground, and boxes can be customized with pre-wiring or high-flex cables.

Summary

When selecting a distribution box, the port type (M8, M12, M16) determines the physical dimensions of the cable entry, while pre-wired cable lengths, coding, and IP rating ensure compatibility with your system. For industrial automation, robotics, or processing applications, these specifications are critical for reliable and safe connections.
