Omron D4JL-2NFA-D5 Safety Door Switch
Omron D4JL-2NFA-D5 is a guard lock safety door switch designed for protective machine access with a special release key. Its mechanical lock with solenoid release controls guard locking, while the 2NC/1NO + 2NC/1NO contact configuration provides switching paths for guard and lock status monitoring. A G1/2 conduit supports machine wiring, and the Type 2 low-level coded interlock provides mechanical guard-position detection. IP67 protection supports industrial installations, with 60 N minimum direct opening force and 15 mm minimum travel. The D4JL-2NFA-D5 belongs to the D4JL series within the machine guard lock switch range from Omron machine safety products, supporting protective doors and controlled machine access.

The Omron D4JL-2NFA-D5 Guard Lock Safety Door Switch combines a mechanical lock with solenoid release for controlled access through protective machine doors. A special release key forms part of the access-release arrangement, while the 2NC/1NO + 2NC/1NO contact configuration provides multiple switching paths for guard and lock status monitoring. A G1/2 conduit supports machine wiring, and a Type 2 low-level coded interlock provides mechanical guard-position detection.
The direct opening mechanism provides 60 N minimum force with 15 mm minimum travel, while operating speed ranges from 0.05 to 0.5 m/s. IP67 protection supports industrial machine safety installations. For model relevance, the important relationships are guard locking, solenoid release, special release key, contact monitoring, protective-door detection and machine access control. Together, these attributes establish the D4JL-2NFA-D5 as part of a guard lock safety system rather than simply another mechanical switch. The mechanical lock controls the protective guard, while the electrical contacts provide status paths for the associated safety circuit. This structure gives search engines and users clear context around entity, function and application without relying on weight or low-value electrical specifications. For another supplied D4JL model with the same mechanical lock, G1/2 conduit and 2NC/1NO + 2NC/1NO configuration, the D4JL-2NFA-C5 provides the closest sibling relationship.
