Omron D4A Series Roller Lever Limit Switch, 1 NO/1 NC, IP67, Metal Housing

This limit switch is a compact industrial actuator designed to detect mechanical position changes and provide reliable electrical switching in automated systems. Housed in a robust metal enclosure with a roller lever actuator, it is intended for multi-orientation mounting and integration where snap-action contact operation and clear changeover signalling between one normally open and one normally closed contact are required.

• Snap-action contacts deliver quick electrical transition for accurate control
• Mechanical rating of 10,000,000 cycles ensures prolonged operational life
• IP67 ingress protection permits use in wet or dusty environments
• Screw terminals provide secure field wiring connections
• M12 conduit entry simplifies conduit and cable gland attachment

• Suitable for conveyor position sensing in production lines
• Ideal for limit detection on industrial automation equipment
• Used with actuated doors and safety interlock mechanisms
• Can be used for machine stroke end-of-travel detection

It offers a single changeover contact set with one normally open and one normally closed contact operating via a snap-action mechanism.

It carries multiple recognitions including CE, CSA, UL, CCC and meets RoHS requirements for restricted substances.

It is rated to function reliably at ambient temperatures from -10°C up to 80°C.

The metallic enclosure provides enhanced mechanical protection and suitability for heavy-duty applications where impact resistance is required.
