It uses a mechanical lock that holds the door closed until the 24VDC solenoid is energized to release it, so power loss keeps the door locked – a fail-safe arrangement for hazard zones. The built-in switch configuration is 3NC + 2NC, giving five normally-closed contacts for redundant monitoring of the lock and door position. The AC-15 rating of 5A at 120V ac covers solenoid and contactor loads typical in control circuits – that's the current it can switch reliably when driving inductive loads like the lock solenoid itself or a downstream safety relay. The DC-13 rating of 22A at 125V dc is unusually high for a safety switch; it handles DC brake solenoids or large DC valve coils without derating. Both ratings are per IEC 60947-5-1, so they define the switching capacity under inductive conditions, not just resistive break. ## Deployment context This switch mounts on the door frame with the resin head facing the door; the G1/2 conduit entry (2 = G1/2) accepts standard metal or plastic conduit for cable protection in industrial environments. The resin head material (F = Resin) is lighter than metal and avoids corrosion in washdown areas, but it's not rated for impact-heavy applications – check the application for mechanical abuse risk. The 24VDC orange LED indicator (D = 24VDC) gives a quick visual on solenoid power without a meter.","metaTitle":"Omron D4SL-N2HFA-D4C3 Safety Door Electromagnetic Lock Switc","metaDescription":"Safety door electromagnetic lock switch with mechanical lock/24VDC solenoid release.
