Omron D4F Series Roller Plunger Safety Limit Switch, 1 NO/1 NC, IP67

This safety limit switch is a Compact electromechanical actuator designed to detect position and interrupt circuits within industrial control systems. It is suited to equipment requiring a robust, ingress-protected switching element with clear make/break contacts and a roller plunger actuator for direct mechanical engagement.

• IP67 enclosure protects against dust ingress and temporary immersion
• 1NO 1NC contact set permits both make and break sensing
• Slow action contacts minimise contact bounce during switching
• 12 N operating force enables consistent actuation with modest input loads
• Mechanical endurance rated for 120 operations supports intermittent use
• Terminal earth connection simplifies earthing arrangements for installations

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for safety interlock on machine guards and access panels
• Used with packaging machinery for position confirmation of actuators
• Can be used for limit sensing on automated material-handling equipment

It functions across a low of −30°C up to a high of 70°C, allowing use in many industrial environments.

The roller plunger permits linear contact with moving parts and accommodates slight lateral motion, reducing alignment sensitivity during mounting.

With a 30mm width it occupies minimal lateral space, facilitating tight layouts on control panels or assembly frames.
