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

The Omron D4NL-1CFG-B Guard Lock Safety Door Switch combines a 24 VDC solenoid lock with mechanical release for controlling access through protective machine doors. Its 2NC + 1NC/1NO contact configuration provides multiple switching paths for monitoring guard and lock conditions within the associated safety circuit. 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 where guarded access must be monitored. The defining relationships are solenoid locking, mechanical release, 2NC + 1NC/1NO contacts, protective-door detection and machine access control. These functional attributes create stronger product context than adding secondary electrical or environmental values. The solenoid secures the protective guard, while the mechanical release provides the corresponding release method and the contacts communicate status to the machine safety system. An orange LED supports 10 to 115 VAC/VDC indication for visible operating status. Within the D4NL family, contact arrangement and locking principle provide useful criteria for comparing individual guard lock models. For a G1/2 model using the same 2NC + 1NC/1NO contact configuration and solenoid-lock principle, the D4NL-2CFG-B provides a closely related configuration.
