Hirschmann Circular Connector, 4 Contacts, Cable, M22 Connector, Socket, Female, IP67, CA Series

Belden Series CA Circular Connector, 16A Current, 400V Voltage - 934125100 CA 3 LD

This circular connector provides a waterproof, cable-mounted electrical Interface for industrial installations. Designed for straight mating, it accommodates a female socket with a 3+PE 4-contact arrangement and offers compatibility with medium-power distributions in automation and machinery environments. The housing is formed from a high-performance polyamide, enabling use across a broad temperature span in demanding site conditions.

Features & Benefits

• Rated for 16A current enabling medium-power circuit connections
  Withstands up to 400V for three-phase and protective earth systems
  Silver-plated brass contacts reduce contact resistance and corrosion
  Screw termination ensures secure conductor clamping under vibration
  IP66 and IP67 protection prevents dust ingress and temporary immersion
  Operates from -40 °C to 90 °C for varied temperature environments

**Applications**

• Suitable for sensor and actuator cabling in automated production lines
  Ideal for power distribution to small motors and drives
  Used with control panels requiring waterproof cable entries
  Can be used for field junctions on outdoor electrical equipment

What contact arrangement does it support for protective earth?

It uses a 3-pole Plus protective earth layout that separates PE from live conductors for safe earthing in four-conductor cabling.

How is the connector secured to conductors during installation?

Termination is via screw clamps that permit straightforward conductor insertion and reliable mechanical retention under movement.

How does the material choice affect field durability?

The polyamide 66 body gives mechanical resilience and chemical resistance suitable for industrial exposure while maintaining dimensional stability.

What mating orientation and form factor should be expected on-site?

The connector mates in a straight configuration and presents a circular Shell with a 30.6mm diameter Interface for panel and cable compatibility.
