Omron D4GS-N2T Safety Door Switch
Omron D4GS-N2T is a slim safety door switch designed for monitoring protective doors and movable machine guards in compact installations. Its Type 2 low-level coded interlock provides mechanical guard-position detection, while IP67 enclosure protection supports demanding industrial environments. 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. Electrical isolation is supported by a 250 V rated insulation voltage and 100 MΩ minimum insulation resistance. The D4GS-N2T belongs to the D4GS series within the slim safety door switch range from Omron machine safety products.

The Omron D4GS-N2T Safety Door Switch uses a Type 2 low-level coded interlock with IP67 enclosure protection for compact machine-guard monitoring. Operating speed ranges from 0.1 to 0.5 m/s, while the direct opening mechanism provides 60 N minimum force with 10 mm minimum travel. These characteristics support positive mechanical contact opening when the protective guard changes position. Its integrated cable provides the electrical connection for installation within machine safety circuits.
Contact resistance varies according to cable length, with 300 mΩ maximum for a 1 m cable, 500 mΩ maximum for 3 m and 700 mΩ maximum for 5 m. 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, while 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%. For another N2 configuration in the D4GS family, the D4GS-N2R-5 provides a closely related model.
