Omron D4BL-2DRG Safety Door Switch
Omron D4BL-2DRG is a 24 VDC guard lock safety door switch designed to control access through protective machine doors. It uses a solenoid lock and G1/2 conduit connection, combining electrical guard locking with mechanical safety-door monitoring. A Type 2 low-level coded interlock provides guard-position detection, while IP67 enclosure protection supports industrial machine installations. The direct opening mechanism provides 19.61 N minimum force with 20 mm minimum travel, and the switch supports operating speeds from 0.05 to 0.5 m/s. The D4BL-2DRG belongs to the D4BL series within the guard lock safety switch range from Omron industrial safety products for machine access protection.

The Omron D4BL-2DRG Guard Lock Safety Door Switch operates at 24 VDC and uses a solenoid lock to control access through protective machine doors. Its G1/2 conduit connection provides the wiring entry, while a Type 2 low-level coded interlock supports mechanical guard-position detection. IP67 enclosure protection supports industrial machine safety installations where dust or moisture may be present. The combination of guard locking and door-position monitoring connects the switch directly with machine access control and protective guard interlocking.
The direct opening mechanism provides 19.61 N minimum force with 20 mm minimum travel, supporting positive mechanical contact opening when the associated guard is operated. The switch supports operating speeds from 0.05 to 0.5 m/s. For model selection, its important attributes are the 24 VDC supply, solenoid locking method, G1/2 conduit, Type 2 interlock and direct opening mechanism. These characteristics establish clear semantic relationships between the D4BL-2DRG, guard lock safety switches, protective doors, machine guards and industrial safety circuits without filling the page with secondary specifications. A solenoid-lock configuration is particularly relevant where the machine safety design requires electrical control of the guard locking function. For another 24 VDC D4BL model with mechanical locking instead of solenoid locking and the same G1/2 conduit format, the D4BL-2CRA-A provides a useful related configuration.
