Omron D4GS-N2R Safety Door Switch
Omron D4GS-N2R is a slim safety door switch designed for protective guard monitoring where compact installation is required. A Type 2 low-level coded interlock provides mechanical guard-position detection, 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 suits industrial machine safety installations exposed to dust or moisture. The D4GS-N2R belongs to the D4GS series within the slim safety door switch range from Omron industrial safety products, supporting compact machine guards, protective doors and safety interlock systems.

The Omron D4GS-N2R Safety Door Switch provides a slim mechanical guard-monitoring solution for machines where installation space around the protective door is limited. A Type 2 low-level coded interlock supports guard-position detection, while the direct opening mechanism provides positive mechanical contact separation when the protective guard is operated. IP67 enclosure protection supports industrial machine safety installations where resistance to dust and moisture is required.
The switch supports operating speeds from 0.1 to 0.5 m/s and provides 60 N minimum direct opening force with 10 mm minimum travel. Its slim D4GS construction creates strong relationships with compact safety door switching, protective guard detection, machine access monitoring and industrial safety circuits. These functional attributes are more useful for model relevance than filling the page with contact resistance, weight or other secondary values. The integrated cable arrangement provides connection to the associated machine safety system, while the low-level coded interlock identifies the mechanical guard relationship defined for the D4GS series. When selecting between D4GS models, variant, cable configuration and installation requirements can therefore be considered alongside the common safety-door characteristics. For another N2R model in the supplied D4GS range with the same core slim safety door switch function but a specified cable-length variant, the D4GS-N2R-5 provides a closely related option.
