It gives you 1 normally-open and 3 normally-closed contacts — that NC-heavy stack is what you wire into the safety circuit so the machine can't start with the guard open. Rated to switch 3 A at 240 V AC or 270 mA at 250 V DC, so it'll handle pilot-duty control loads and small solenoids without a contactor in between. The mechanical life is rated at 1 million cycles, electrical at 500,000 — that's a solid run for a guard-door switch in a production line. The body measures 88.5 mm wide by 95 mm tall by 35.5 mm deep — it'll fit on a standard 40 mm profile rail or a flat panel bracket. Screw terminals mean you land your wires with a #2 Phillips; no special crimp tool needed on the line. IP67 rating means the housing and the key-entry seal hold up to washdown and hose spray. Out here in the grease, that's what keeps the contacts from corroding shut on a coolant-soaked press guard. The head rotates to four directions, so you can run the actuator in from the top, bottom, left, or right without buying a different part number.","metaTitle":"Omron D4NL1CFAB Safety Door Lock Switch, 1NO/3NC, IP67, Scre","metaDescription":"Safety door lock switch with mechanical lock, 1NO/3NC contacts, IP67, screw terminal.
