The Siemens 3SE3 120-1E is a position switch with a roller lever actuator, rated for 6 A at 230 V switching voltage. The snap-action 1NO+1NC output configuration gives you one normally-open and one normally-closed contact pair — enough for a basic interlock or limit-sensing circuit without an extra relay.
The IP67 rating means the switch body and roller lever survive washdown environments — food processing, outdoor conveyors, or wet machining lines. Cable entry connection keeps wiring simple: bring the cable in through the gland, terminate to the screw terminals inside, and the snap-action mechanism gives a clean break on opening, reducing arcing on slow-moving cams.
