Omron D4GS-N2R 5 Safety Door Switch
Omron D4GS-N2R 5 is a slim safety door switch designed to detect the position of protective machine guards in space-limited installations. A Type 2 low-level coded interlock provides mechanical guard monitoring, while the direct opening mechanism supports positive contact separation when the protective door is operated. The switch provides IP67 enclosure protection and operates at speeds from 0.1 to 0.5 m/s. Its direct opening mechanism provides 60 N minimum force with 10 mm minimum travel, and the integrated cable supports electrical connection within machine safety systems. The D4GS-N2R 5 belongs to the D4GS series within the machine safety door switch range from Omron industrial safety products.

The Omron D4GS-N2R 5 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 mechanical characteristics support positive contact opening when the associated protective door changes position. The integrated cable provides the electrical connection for use within machine safety circuits where a slim switch construction is required.
Contact resistance varies with cable length: 300 mΩ maximum with a 1 m cable, 500 mΩ maximum with a 3 m cable and 700 mΩ maximum with a 5 m cable. The 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. The operating temperature extends from −30 to 70°C with no icing, humidity is rated up to 95%. The UL2464 No. 22 AWG cable has a 7.2 mm finished outer diameter. For another closely related D4GS model from the same slim safety switch family, the D4GS-N1R-5 provides a related configuration.
