The 'A' in the code means mechanical lock with 24 VDC solenoid release — power to the solenoid unlocks the door, so a loss of power keeps it locked (fail-safe). The switch block is 3NC + 2NC, giving you three normally-closed safety channels and two normally-closed monitor contacts for the control circuit. Metal head (D) and a G1/2 conduit outlet (2) make this variant suited for environments where the switch takes mechanical abuse and the wiring runs through a standard metric/PF conduit. Connection is via terminal block inside the housing, so no special tooling needed on site. The 24 VDC solenoid release (orange LED indicator) tells you the coil voltage and gives a visual status — the LED is on when the solenoid is energized (door unlocked). That LED is a quick diagnostic for the panel builder or field tech: no light means the door is locked and the solenoid circuit is dead, which is the safe state. Standard release key (metal) means the actuator key is a metal tongue that mates with the switch head. The metal head and metal key together handle repeated door cycles without wearing out the engagement point. If you're replacing a switch on a guard door that cycles hundreds of times per shift, the metal construction matters for longevity.","metaTitle":"Omron D4SL-N2HDA-D Guard Lock Safety-door Switch, 24VDC Sole","metaDescription":"Guard Lock Safety-door Switch with mechanical lock and 24VDC solenoid release.
