Omron Safety Rated Interlock Switch with Hinge Actuator, Plastic Housing, IP67, 240V AC, 3A Current D4NH

Omron D4NH Safety Rated Interlock Switch with model code D4NH is designed for safety guarding in industrial automation environments requiring reliable machine stoppage when protective doors open. This switch features a compact hinge-lock design with a plastic enclosure, offering IP67 ingress protection to ensure trustworthy operation even in wet or contaminated environments.

The device includes a hinge actuator and supports both AC and DC control circuits operating at 240V AC and 250V DC contact voltages respectively, with a 3A switch contact current rating. Its slow-action contacts provide direct-opening normally closed (NC) protection, ensuring forced separation of contacts even under metal deposition conditions to maintain safety integrity.

Operating temperatures range from -30°C up to 70°C, making it suitable for varied industrial climate conditions. The switch's four-direction head orientation allows installation flexibility in confined spaces. An M20 conduit entry facilitates standard European cable entry fittings.

Common applications include safety interlock guarding on machine access doors, integration into production lines for interlock circuits with safety equipment requiring forced NC contact separation, and retrofitting existing space-constrained control panels. The switch carries UL, CCC, and CE approvals, validating its compliance with recognized safety and quality standards.
