HARTING Circular Connector, 4 Contacts, Cable, M12 Connector, Plug, Male, IP67, Circular Connectors M12 Series

Harting Circular connectors M12 Series Circular Connector, 4A Current, 4 Contacts - 21033891402

This circular connector provides a robust, D-coded Interface for four-conductor cable assemblies in industrial control and sensor networks. Designed for inline cable mounting with a screw-on mating, it offers a secure electrical connection where environmental sealing and Compact size are required. The device operates across a typical industrial voltage and current envelope and is suited to applications exposed to moderate temperature variation.

Features & Benefits

• Gold-over-nickel contacts deliver low-resistance conductivity
  Brass contact construction resists wear during frequent mating
  Die-cast zinc housing provides mechanical durability and shielding
  IP67 ingress protection enables use in wet and dusty environments
  Screw termination supports secure, tool-assisted conductor fixing
  Operates from -30°C to 85°C for varied ambient conditions

**Applications**

• Suitable for sensor and actuator cabling in factory automation
  Ideal for inline connections on mobile machinery and conveyors
  Used for field wiring in industrial control cabinets requiring sealed terminations
  Can be used for M12-rated communications between modules in harsh areas

What electrical capabilities does it support for signal and power?

It is rated for up to250V and a continuous current of4A, appropriate for low-power signal and certain auxiliary power circuits.

How is the connector physically mounted in an installation?

The unit is a cable-mount straight plug that is secured to its mating part via a screw-on coupling for a positive mechanical joint.

What materials contribute to contact longevity under repeated cycles?

Contacts are machined from brass and finished with gold over nickel plating to reduce contact resistance and improve endurance.

What environmental temperatures can be expected during operation?

The connector is specified to function between -30°C and85°C, covering many indoor and outdoor industrial settings.
