RUKO KES-FormC-82°-7/8 4-Pin Male Screw Termination Circular Connector, IP67, 300 V, 9 A, Silver-Plated Contacts, Polyamide Housing

The RUKO GMBH KES-FormC-82°-7/8 is a field-termination circular connector engineered for industrial signal and power connections where a secure screw lock and robust environmental sealing are required. Its 7/8" form factor with 4 silver-plated brass contacts supports currents up to 9 A and voltages up to 300 V, making it suitable for sensors, actuators, and automation equipment. The straight male connector accepts cable diameters from 6 to 12 mm and uses screw termination for reliable, serviceable wiring without special tooling.

Highlights

• 7/8" circular connector, male, 4-pin, straight orientation
• Screw termination for cable diameters 6–12 mm
• Rated 300 V / 9 A, IP67 when mated
• Polyamide housing, silver-plated brass contacts
• Operating temperature -25 °C to +85 °C, >100 mating cycles

In daily use

The screw-lock mechanism prevents accidental disconnection in vibrating environments, while the IP67 rating ensures reliable operation in dusty or wet conditions. The polyamide housing provides durability and electrical insulation, and the silver plating on contacts maintains low contact resistance over repeated mating cycles.
