Product information

Description

The Harting HARAX M12 4‑pole D‑coded connector is a circular industrial signal and data connector designed for reliable transmission in automation and control environments. Featuring four contacts arranged in D‑coding, the connector reduces the risk of mismating with other M12 types while supporting sensor, actuator and fieldbus wiring. Its compact circular design and robust contact system provide consistent electrical performance for industrial signal and Ethernet-like data lines used in factory and process automation.

Advantages

The M12 4‑pole D‑coded configuration ensures correct mating with compatible D‑coded receptacles, minimising connection errors. The connector delivers stable contact resistance and is built to withstand the mechanical and electrical demands of industrial installations. Its circular form factor and proven HARAX design allow straightforward integration into sensor and actuator networks, while D‑coding supports signal and data separation to meet system requirements.

Suitable for

  • Sensor and actuator connections in industrial automation
  • Fieldbus and industrial Ethernet signal lines requiring D‑coding
  • Panel and machine wiring in control cabinets and distributed I/O
  • Applications where robust, compact circular connectors are needed

Key specifications

  • Connector type: circular M12 with 4 contacts
  • Coding: D‑coded to prevent mismating with other M12 codings
  • Contact count: 4 contacts suitable for signal and data pairs
  • Contact materials and plating: designed for low contact resistance and reliable conductivity
  • Mechanical design: compact circular housing for panel or pre‑wired mounting
  • Environmental suitability: intended for industrial electrical environments (mechanical robustness and stable contact performance)

How to use

Install the connector by aligning the D‑coding key with the matching receptacle to ensure correct orientation. Secure the connector to the mating part or panel according to mounting provisions, and verify that contacts engage fully to achieve low resistance connections. Use compatible cable types and follow standard wiring practices for signal or data pairs. Ensure proper strain relief and, where applicable, routing that minimises mechanical stress and exposure to excessive vibration.

Usage recommendations

Use the connector in systems that require clear separation of signal and data paths and where mating reliability is important. Regularly inspect contacts and housings for wear or contamination in harsh environments, and follow the equipment manufacturer's guidelines for torque and mounting to maintain connection integrity.
