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

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.

• 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

• 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

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

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

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

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