Omron D4NL-1AFG-B Safety Door Switch
Omron D4NL-1AFG-B is a 24 VDC guard lock safety door switch designed to control access through protective machine doors. It uses solenoid locking with mechanical release, while the 1NC/1NO + 1NC/1NO contact configuration provides separate switching paths for guard and lock status monitoring. A Type 2 low-level coded interlock supports mechanical guard-position detection, with 60 N minimum direct opening force and 10 mm minimum travel. IP67 protection supports industrial machine safety installations requiring controlled access. The D4NL-1AFG-B belongs to the D4NL Series within the guard lock safety switch range from Omron industrial safety products, connecting guard locking, protective access and safety circuit monitoring.

The Omron D4NL-1AFG-B Guard Lock Safety Door Switch operates with a 24 VDC solenoid and uses solenoid locking with mechanical release for controlled access through protective machine doors. Its 1NC/1NO + 1NC/1NO contact configuration provides separate switching paths for monitoring guard and lock conditions. A Type 2 low-level coded interlock supports mechanical guard-position detection, while the direct opening mechanism provides 60 N minimum force with 10 mm minimum travel. IP67 enclosure protection supports industrial machine safety installations requiring guarded access control. The important relationships for this model are solenoid guard locking, mechanical release, contact monitoring, protective-door detection and machine safety control. These characteristics provide useful product context without depending on low-value specifications such as weight or resistance values. The solenoid controls the locking function, while the mechanical release provides the defined release method and the contacts communicate guard and lock conditions to the associated safety circuit. An orange LED supports 10 to 115 VAC/VDC indication for visible operating status. Locking method and contact arrangement are therefore useful attributes when comparing models within the D4NL Series. For a G1/2 D4NL model with the same contact arrangement and solenoid-lock principle, the D4NL-2AFG-B provides a closely related configuration.
