It uses a key-actuated, 4-head-direction design — you can route the actuator from any of four orientations, which helps when the guard frame is tight or the door hinge is on the wrong side. Rated for switching 1.5 A at 120 V AC or 220 mA at 125 V DC, with 4NC contacts. That's a low-current safety circuit — think PLC safety input loops or contactor feedback, not motor power. The IP67 rating means it handles washdown and dust on the factory floor without a secondary enclosure. The body measures 39 mm wide by 39 mm deep and 180 mm tall — a slim profile that fits in a standard 40 mm DIN-rail footprint or direct panel mount. Terminal block wiring, no pigtails to chase.","metaTitle":"D4SLN4DFG Guard Lock Safety-Door Switch, 4NC, IP67","metaDescription":"D4SLN4DFG guard lock safety-door switch, 4NC contacts, IP67, terminal block. 1.5 A AC / 220 mA DC.
