Omron D4SL-N2AFG-D Safety Door Switch, AC-15 5A/120V ac, DC-

The Omron D4SL-N2AFG-D is a safety door electromagnetic lock switch — the kind that physically holds a guard closed until the control system releases the solenoid, then lets an operator open the door. The built-in switch configuration is 1NC/1NO + 1NC/1NO, giving two independent safety channels plus two auxiliary feedback contacts. The AC-15 rating of 5A at 120V ac tells you the contacts are designed for solenoid and contactor control loads — inrush-heavy, not resistive. The DC-13 rating of 22A at 125V dc covers the DC interlock or brake circuits common in European-style safety chains. The solenoid itself is 24VDC, with an orange LED indicator to show when it's energised. The G variant in the order code means it's a 24VDC solenoid lock with mechanical release — so if power drops, the lock stays engaged until you manually release it with the special resin key. That matters for vertical or press-guarding applications where a power-loss unlock could drop a gate or create a pinch point.
