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

This safety limit switch is a compact, high-sensitivity actuator intended for machine safety and position sensing in industrial automation. Housed in metal with an IP67 rating, it provides a sealed switching element with slow-action contacts and a cable outlet for direct wiring. The unit operates across a wide ambient temperature range and is designed for frequent mechanical cycling in small-scale machinery and equipment.

• 2NO/2NC contact construction supports separate safety and signalling circuits
• 12N operating force ensures positive actuation with roller plunger
• Rated for 240V AC switching at 0.75A for control and signalling loads
• Operating range −30°C to 70°C permits use in varied indoor environments
• Metal housing with IP67 sealing protects against dust and temporary immersion

• Suitable for Compact machine end-of-travel position monitoring
• Ideal for small automated conveyors and feed mechanisms
• Used with safety circuits requiring slow-action contact behaviour
• Can be used for limit detection on toolroom fixtures and jigs

The switch uses an integral cable Terminal with multiconductor cable finished to a nominal outer diameter for direct connection

Mechanical endurance is specified to 10 million operations with electrical durability rated separately for resistive loads, and electrical endurance varies with load and switching frequency.

The unit is offered with a roller plunger actuator that provides a short movement angle for Rapid response and can be mounted with the cable exiting in different directions to suit layout.
