Quick Selection Guide

Choose the Hirschmann 933138-100 when UL listing is required or when the cable outside diameter is between 4.5 and 6 mm. Choose the OMAL M509ZRB270310 when a shorter 24 mm connector body, a 4 to 6 mm cable range or a glass-fiber-reinforced housing is preferred. Both connectors provide the same contact spacing, electrical rating, and ingress protection.

What Are DIN 43650 Form C Connectors Used For?

DIN 43650 Form C connectors provide a compact, field-wireable electrical connection for compatible solenoid valves and other industrial control devices. Their screw terminals simplify onsite wiring, while the PG 7 entry supports small-diameter control cable in space-limited equipment.

Before Ordering

Confirm the pin spacing (as other Form Cs that are available have 8mm spacing), cable outside diameter, connector dimensions, voltage and current requirements, and other specs on the product pages. The IP65 rating depends on correct assembly with compatible cable and sealing components.
