Omron D4GS Series Door Micro Switch, IP67, 1m Length - D4GS-N3R


This door micro switch is a compact, industrial-grade limit device designed to detect door position and provide reliable contact signalling in harsh environments. It employs an operation key actuator and a mixed contact arrangement to control circuits where distinct normally open and normally closed responses are required. The enclosure offers ingress protection suitable for wet or dusty conditions, and the component is specified for a broad ambient temperature range to suit demanding installations.

Features & Benefits


• 1NO2NC contact layout for flexible circuit control and safety integration
• IP67 enclosure providing waterproof protection during washdown
• 60N actuation force ensuring consistent operation under mechanical load
• Rated for operation up to 70°C to tolerate elevated ambient temperatures
• Endurance of 1,000,000 operations supporting long maintenance intervals

**Applications**


• Suitable for door position detection in automated assembly lines
• Ideal for access panels in food-processing environments requiring washdown
• Used for safety interlocks on industrial cabinetry and machinery guards
• Can be used for control feedback in material-handling equipment

What temperatures can the switch reliably withstand during continuous service?


It is specified to operate between −30°C and 70°C, covering sub-zero storage areas through heated process zones.

How does the contact configuration aid integration with control systems?


The single normally open and two normally closed contacts allow simultaneous signalling to separate circuits such as control logic and safety relays.

What mechanical lifespan can installers expect before replacement is needed?


The device is specified for 1,000,000 operations, indicating suitability for high-cycle applications with predictable replacement planning.

Which approvals indicate its suitability for international industrial use?


It holds CCC, CE, CULUS Listed and TÜV approvals, reflecting compliance with multiple regional safety and performance standards.
