Omron D4GS-N1T Safety Door Switch
Omron D4GS-N1T is a slim safety door switch designed for monitoring protective doors and machine guards where compact installation is required. Its 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 IP67 enclosure protection and supports operating speeds from 0.1 to 0.5 m/s. A 60 N minimum direct opening force and 10 mm minimum travel define its mechanical opening characteristics, while an integrated cable provides the electrical connection. The D4GS-N1T belongs to the D4GS series within the slim safety door switch range from Omron machine safety products.

The Omron D4GS-N1T Safety Door Switch uses a Type 2 low-level coded interlock with IP67 enclosure protection for protective-door monitoring in compact machine installations. It operates at speeds from 0.1 to 0.5 m/s and provides 60 N minimum direct opening force with 10 mm minimum travel. The direct opening mechanism supports positive mechanical contact separation when the associated guard is operated. Its integrated cable provides the connection between the safety door switch and the machine safety circuit.
Contact resistance is specified according to 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. Electrical ratings include a 250 V rated insulation voltage, 100 MΩ minimum insulation resistance and a 2 × 2 mm minimum contact gap. 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. The operating temperature extends from −30 to 70°C with no icing, ambient humidity is rated up to 95%. Its UL2464 No. 22 AWG cable has a 7.2 mm finished outer diameter. For a related D4GS configuration from the same slim safety switch family, the D4GS-N1R-5 provides a closely related model.
