Omron D4NL-2CFG-B Safety Door Switch
Omron D4NL-2CFG-B is a 24 VDC guard lock safety door switch using a solenoid lock with mechanical release for protective machine access. Its 2NC + 1NC/1NO contact configuration supports guard and lock status monitoring, while a G1/2 conduit provides the machine wiring connection. A Type 2 low-level coded interlock supports mechanical guard-position detection, and IP67 protection suits 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. The D4NL-2CFG-B belongs to the D4NL series within the machine guard lock switch range from Omron machine safety products, supporting protective doors and controlled access.

The Omron D4NL-2CFG-B Guard Lock Safety Door Switch uses a 24 VDC solenoid lock with mechanical release for controlled access through protective machine doors. Its 2NC + 1NC/1NO contact configuration provides multiple switching paths for guard and lock status monitoring. A G1/2 conduit supports machine wiring, while the Type 2 low-level coded interlock provides mechanical guard-position detection. IP67 enclosure protection supports industrial machine safety installations where resistance to dust and moisture is required.
The direct opening mechanism provides 60 N minimum force with 10 mm minimum travel, and operating speed ranges from 0.05 to 0.5 m/s. An orange LED supports 10 to 115 VAC/VDC indication for visual status information. The defining relationships for this model are solenoid locking, mechanical release, G1/2 wiring, contact monitoring and protective-door access control. These attributes connect the D4NL-2CFG-B with guard lock safety switches, machine guards, safety interlocks and industrial control circuits. The solenoid-lock principle distinguishes this version from D4NL models using mechanical locking with solenoid release, making lock behavior an important selection factor. Contact configuration and conduit type further define the model within the D4NL family. For another D4NL model using the same 2NC + 1NC/1NO contact configuration but mechanical locking with solenoid release, the D4NL-1CFA-B provides a useful related configuration.
