Omron D4NH Safety Rated Interlock Switch, Hinge Actuator Included, Plastic, Hinge

This safety-rated interlock switch is a Compact hinge-lock device intended to monitor guard doors and safety equipment in industrial automation and machinery settings. It operates as a safety interlock with an integral actuator and provides fail-safe separation of normally closed contacts during guard opening, making it suitable for machine safety circuits where direct opening operation is required.

• IP67 protection for immersion resistance and sealed environments
• 3A contact rating for switching standard control loads
• Operates at 240V AC and 250V DC for versatile supply use
• Four head mounting directions for flexible installation
• Plastic housing reduces weight and offers double-insulation protection
• Rated for operation from -30°C to 70°C for high-temperature use

• Suitable for guarding access panels on production machinery
• Ideal for safety circuits in packaging and assembly lines
• used with interlocked doors on electrical cabinets and enclosures
• Can be used for safety monitoring of robotic cell barriers
• Suitable for retrofit where M20 conduit connection is required

The switch accepts an M20 conduit entry enabling use of M-style cable glands and European-style conduit fittings.

The NC contacts incorporate a direct opening mechanism that forces separation even if metal deposition occurs, maintaining safe circuit interruption.

Mechanical endurance is specified at a minimum of 1,000,000 operations and electrical endurance up to 500,000 operations for a resistive 3A load at 250VAC.

Yes, the head can be remounted in four orientations by removing the head screws to suit installation requirements.
