Omron D4F Series Roller Lever Safety Limit Switch, 2 NO/2 NC, IP67

This safety limit switch provides electromechanical position detection for industrial control applications, using a roller lever actuator to monitor moving parts and initiate safety or control responses. It is designed for use in environments where ingress protection and a broad operating temperature range are required, and it meets multiple international approval standards for deployment in automated systems.

• 2NO2NC contact arrangement enables flexible control and safety wiring
• IP67 rating permits operation in wet or dusty conditions
• Mechanical endurance of 10000000 operations supports long service intervals
• Operating temperature span -30 to 70°C maintains functionality in extremes
• 5 N operating force allows precise actuation with minimal load
• Certified to UL EN CCC for international regulatory acceptance

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for machine guard position monitoring in assembly plants
• Used for automated door position sensing in industrial facilities
• Can be used for actuator limit detection in material handling systems

It provides two normally open and two normally closed contacts to support simultaneous control and safety circuits without additional relays.

With an IP67 enclosure it resists dust ingress and temporary immersion, allowing reliable switching in challenging environments.

The device is rated for ten million mechanical operations, which aids long-term maintenance scheduling and reduces replacement frequency.

The roller lever requires an operating force of 5 N, permitting use with light-touch mechanisms and precise cam profiles.
