Omron D4JL-2RFG-C5 Safety Door Switch
Omron D4JL-2RFG-C5 is a guard lock safety door switch designed with a special release key for controlled access to protected machine areas. It uses a solenoid lock with mechanical release and a 3NC + 3NC contact configuration for guard and lock status monitoring. A Type 2 low-level coded interlock provides mechanical guard-position detection, while a G1/2 conduit supports cable entry. The IP67-rated switch operates from 0.05 to 0.5 m/s and provides 60 N minimum direct opening force with 15 mm minimum travel for positive contact opening. The D4JL-2RFG-C5 belongs to the D4JL series within the machine guard lock switch range from Omron machine safety products.

The Omron D4JL-2RFG-C5 Guard Lock Safety Door Switch uses a special release key with a solenoid lock and mechanical release arrangement for controlled access to guarded machinery. Its 3NC + 3NC contact configuration provides multiple normally closed switching paths for guard and lock monitoring. A Type 2 low-level coded interlock provides mechanical guard detection, while the G1/2 conduit supports cable entry. IP67 enclosure protection supports industrial installations, and the switch operates at speeds from 0.05 to 0.5 m/s with 60 N minimum direct opening force and 15 mm minimum travel.
Electrical ratings include 25 mΩ maximum contact resistance, a 300 V rated insulation voltage, 100 MΩ minimum insulation resistance and a 2 × 2 mm minimum contact gap. Rated frequency is 50/60 Hz. Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude. Shock resistance reaches 1,000 m/s² minimum for destruction and 80 m/s² minimum for malfunction. Operating temperature ranges from −10 to +55°C, ambient humidity reaches 95% maximum. Its 3NC + 3NC arrangement differentiates this configuration from D4JL variants using mixed NC/NO contacts. For a related special-release-key model using 2NC/1NO + 2NC/1NO contacts, the D4JL-2NFG-C5 provides a useful related configuration.
