Omron D4NL-2GFG-B Safety Door Switch
Omron D4NL-2GFG-B is a 24 VDC guard lock safety door switch designed for controlled access through protective machine doors. It uses a solenoid lock with mechanical release, while the 3NC + 1NC/1NO contact configuration provides multiple switching paths for guard and lock status monitoring. A G1/2 conduit provides the wiring connection, and a Type 2 low-level coded interlock supports mechanical guard-position detection. IP67 protection suits industrial machine safety installations, with 60 N minimum direct opening force and 10 mm minimum travel. The D4NL-2GFG-B belongs to the D4NL series within the guard lock safety switch range from Omron industrial safety products, supporting machine guards, protective access and safety interlocking.

The Omron D4NL-2GFG-B Guard Lock Safety Door Switch uses a 24 VDC solenoid lock with mechanical release to control access through protective machine doors. Its 3NC + 1NC/1NO contact configuration provides multiple switching paths for monitoring guard and lock conditions within the machine safety circuit. A G1/2 conduit provides the wiring connection, while the Type 2 low-level coded interlock supports mechanical guard-position detection. IP67 enclosure protection supports industrial machine safety installations.
The direct opening mechanism provides 60 N minimum force with 10 mm minimum travel, while operating speed ranges from 0.05 to 0.5 m/s. An orange LED supports 10 to 115 VAC/VDC indication for visible status information. The 3NC + 1NC/1NO contact arrangement is an important differentiator because it provides the model-specific switching structure within the D4NL range. Combined with solenoid locking, mechanical release and G1/2 wiring, it establishes clear relationships with machine guards, protective access control, guard lock safety switches and safety circuit monitoring. These entities provide useful topical relevance without adding low-value technical data merely to increase word count. Lock method and contact arrangement should therefore remain central when comparing related models. For another G1/2 D4NL model using solenoid locking with mechanical release but a 2NC + 1NC/1NO contact configuration, the D4NL-2CFG-B provides a closely related alternative.
