Omron D4n Series Top Plunger Safety Limit Switch, 1 NO/2 NC, IP67

This safety limit switch is a Compact actuator device designed for industrial control and automation installations where mechanical position detection and circuit switching are required. Housed in a plastic enclosure with ingress protection to IP67, it offers slow-action contact operation and is intended for use in machinery, lifts and general-purpose safety monitoring within controlled indoor environments.

• Top plunger actuator provides precise actuation and repeatability
• Contact arrangement 1NO/1NC supports versatile control logic
• Rated switching current 10A for standard industrial loads
• Electrical switching capability up to 250VDC for DC circuits
• Mechanical endurance 15,000,000 cycles for extended service life
• Operational temperature range -30 to 70°C for varied indoor conditions

• Suitable for electromechanical position sensing on conveyor stops
• Ideal for door-interlock detection in lift and escalator systems
• Used for limit detection on industrial packaging machinery
• Can be used for end-of-travel monitoring in actuator assemblies

It is compatible with an M20 conduit entry to suit typical European cable glands and conduit fittings.

The slow-action contact provides controlled make/break transitions appropriate for applications sensitive to contact bounce or requiring gradual switching.

The enclosure meets IP67 degree of protection and is specified for operation without icing between -30 and 70°C.

The device has a rated insulation voltage of 300V and a rated open thermal current Ith of 10A per relevant standards, suitable for the specified AC and DC utilisation categories.
