Omron D4n Series Plunger Limit Switch, 1 NO/1 NC, IP67, Metal Housing

This limit switch is a compact, industrial plunger device designed for position sensing and safety interlock tasks in automation and control systems. Housed in metal with a sealed enclosure, it is intended for indoor industrial environments where dust or temporary immersion resistance is required. The unit provides a single snap-action changeover contact set and is suitable for installations requiring straightforward wiring via screw terminals and standard conduit entry.

• IP67 sealed metal housing for ingress protection and washdown resistance
• Snap-action 1NO/1NC contact for Rapid reliable switching at 250VAC
• Operating force 6.5N reduces actuation wear and improves repeatability
• Mechanical life 15,000,000 cycles for long service intervals
• Operating temperature range −30°C to +70°C for broad industrial use
• Screw terminals and PG13.5 conduit entry for conventional field wiring

• Suitable for end-of-travel detection on conveyor indexing systems
• Ideal for actuator position feedback in assembly machinery
• Used with lift and elevator components complying with EN 115 guidance
• Can be used for machine guard interlocks requiring direct-opening NC contact
• Suitable for test rigs needing high-cycle mechanical durability

Termination is by screw terminals designed for AWG20 to AWG18 (0.5 to 0.75 mm²) conductors and a PG13.5 conduit opening for sealed cable entry.

It is rated for AC switching suitable for standard and micro loads with approved utilisation categories including AC-15 and DC-13

The head is rotatable to multiple directions to accommodate different actuator approaches and mounting positions.

Vibration and shock resistance are specified for industrial environments with malfunction and destruction thresholds tested to ensure durability.
