Omron D40ML Safety Interlock Switch, RFID Actuator Included, Plastic, Guard

This safety interlock switch is designed to monitor and secure access to guarded machinery and electrical enclosures within industrial automation environments. It combines a non-metallic enclosure with an integrated actuator to detect guard positions and interrupt hazardous operations, meeting recognised approvals for use in controlled installations.

• Plastic housing provides a lightweight, corrosion-resistant enclosure
• RFID lock style enables contactless guard monitoring and keyless operation
• Four safety contacts deliver multiple-channel safety signalling
• Includes actuator for immediate installation and commissioning

• Suitable for safeguarding automated production lines with access doors
• Ideal for integration into control panels requiring guarded isolation
• Used for machine tool enclosures where contactless detection is preferred
• Can be used for conveyor guarding systems in washdown zones
• Used with electrical cabinets needing certified safety interlocks

The RFID mechanism removes mechanical wear points by using radio-frequency identification to verify guard position, improving long-term signal consistency.

The enclosure meets IP67, protecting internal circuitry from dust ingress and temporary submersion, suitable for high-humidity or washdown areas.

The unit’s operational range from -25°C to 40°C covers most indoor and refrigerated facilities but should be checked against any process-specific extremes.
