Omron D4GS-N3R-5 Safety Door Switch
Omron D4GS-N3R-5 is a slim safety door switch for monitoring protective doors and movable guards on industrial machinery. Its Type 2 low-level coded interlock provides mechanical guard-position detection, while the direct opening mechanism supports positive contact separation during guard operation. IP67 enclosure protection supports installations exposed to demanding industrial conditions. The switch operates from 0.1 to 0.5 m/s and provides 60 N minimum direct opening force with 10 mm minimum travel. A 250 V rated insulation voltage and 100 MΩ minimum insulation resistance define its electrical isolation characteristics. The D4GS-N3R-5 belongs to the D4GS series within the slim guard switch range from Omron machine safety products.

The Omron D4GS-N3R-5 Safety Door Switch provides Type 2 low-level coded guard interlocking in a slim construction for compact machine installations. IP67 enclosure protection supports use around industrial equipment, while the specified operating speed extends from 0.1 to 0.5 m/s. Its direct opening mechanism provides 60 N minimum force and 10 mm minimum travel, creating positive mechanical contact separation when the protective guard is operated. The integrated cable provides the connection to the associated machine safety circuit.
Contact resistance depends on cable length: 300 mΩ maximum with a 1 m cable, 500 mΩ maximum with 3 m and 700 mΩ maximum with 5 m. The rated insulation voltage is 250 V, insulation resistance is 100 MΩ minimum and 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. The switch withstands 1,000 m/s² minimum destruction shock and 300 m/s² minimum malfunction shock. Its operating temperature extends from −30 to 70°C with no icing, while humidity is rated up to 95%. For the corresponding N3R model within the same D4GS family, the D4GS-N3R provides the closest related option.
