Omron D4GS-N1T-5 Safety Door Switch
Omron D4GS-N1T-5 is a slim safety door switch designed to detect the position of machine guards and protective access doors. Its compact construction supports installations where mounting space is limited, while the Type 2 low-level coded interlock provides mechanical guard-position monitoring. The switch uses a direct opening mechanism with a 60 N minimum opening force and provides IP67 protection for industrial machine safety applications. It supports guard movement speeds from 0.1 to 0.5 m/s and uses an integrated cable connection. The D4GS-N1T-5 belongs to the D4GS series within the slim safety door switch range from Omron machine safety products.

The Omron D4GS-N1T-5 Safety Door Switch uses a Type 2 interlock with low-level coded operation and provides IP67 protection. It supports an operating speed of 0.1 to 0.5 m/s and has a direct opening force of 60 N minimum with 10 mm minimum direct opening travel. The minimum contact gap is 2 × 2 mm, while the rated frequency is 50/60 Hz. These mechanical characteristics support defined guard-position detection and contact opening when the connected protective door is operated.
Electrical specifications include a 250 V rated insulation voltage and 100 MΩ minimum insulation resistance. Contact resistance is 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. Malfunction vibration resistance covers 10 to 55 Hz at 0.35 mm single amplitude. Shock resistance is rated at 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. Operating temperature extends from −30 to 70°C with no icing, with ambient humidity up to 95%. Connection uses a UL2464 No. 22 AWG cable with a 7.2 mm finished outer diameter.
