Omron D4GS-N1R Safety Door Switch
Omron D4GS-N1R is a slim safety door switch designed for monitoring protective doors and movable machine guards where compact installation is important. Its Type 2 low-level coded interlock provides mechanical guard-position detection, while the direct opening mechanism delivers 60 N minimum force with 10 mm minimum travel. The switch supports operating speeds from 0.1 to 0.5 m/s, and IP67 protection suits industrial machine safety applications exposed to dust or moisture. The D4GS-N1R belongs to the D4GS Series within the slim safety door switch range from Omron machine safety products, supporting guard detection, protective access monitoring and machine safety control.

The Omron D4GS-N1R Safety Door Switch provides compact mechanical guard monitoring for protective doors where available installation space is limited. Its Type 2 low-level coded interlock establishes the mechanical relationship between the switch and guard position, while the direct opening mechanism supports positive contact separation when the protective door is operated. The switch provides 60 N minimum direct opening force with 10 mm minimum travel and supports operating speeds from 0.1 to 0.5 m/s. IP67 enclosure protection supports industrial machine safety installations where dust or moisture may reach the device. The main product relationships are slim safety door switching, protective guard detection, direct opening operation, machine access monitoring and safety interlocking. These functional attributes describe the model more clearly than secondary resistance, vibration or weight specifications. Its integrated cable arrangement provides connection to the associated safety circuit, while the compact D4GS design supports installation around guarded machine access points. Within the D4GS family, model selection can focus on mounting arrangement, variant and required cable configuration while retaining the same core protective-door monitoring relationship. For a closely related N1R version with a specified 5 m cable configuration, the D4GS-N1R-5 provides a relevant sibling model.
