Omron D4GS-N1R-5 Safety Door Switch
Omron D4GS-N1R-5 is a slim safety door switch designed for guard-position detection where installation space is limited. A Type 2 low-level coded interlock provides mechanical monitoring of protective doors, while the direct opening mechanism supports positive contact separation when the guard is operated. The switch provides IP67 enclosure protection, operates at speeds from 0.1 to 0.5 m/s and delivers 60 N minimum direct opening force with 10 mm minimum travel. Its integrated cable construction supports connection within compact machine safety installations. The D4GS-N1R-5 belongs to the D4GS series within the slim safety door switch range from Omron industrial safety products.

The Omron D4GS-N1R-5 Safety Door Switch uses a Type 2 low-level coded interlock with IP67 enclosure protection for compact protective-door monitoring. The switch operates at speeds from 0.1 to 0.5 m/s and provides 60 N minimum direct opening force with 10 mm minimum travel. These mechanical characteristics support positive contact opening when the associated machine guard is operated. Its integrated cable construction provides the electrical connection for installation within machine safety circuits.
Contact resistance depends on cable length, with 300 mΩ maximum specified for a 1 m cable, 500 mΩ maximum for a 3 m cable and 700 mΩ maximum for a 5 m cable. Rated insulation voltage is 250 V, insulation resistance is 100 MΩ minimum and the minimum contact gap is 2 × 2 mm. Rated frequency is 50/60 Hz. Malfunction vibration resistance covers 10 to 55 Hz at 0.35 mm single amplitude. Shock resistance reaches 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. Operating temperature ranges from −30 to 70°C with no icing, humidity is rated up to 95%. The cable is UL2464 No. 22 AWG with a 7.2 mm finished outer diameter. For a closely related D4GS configuration, the D4GS-N1T provides another slim safety door switch option.
