Door Interlock Switch Siemens 3SE22430XX40

This Siemens 3SE22430XX40 mechanical limit switch comes as a complete unit with a 52 mm wide plastic enclosure, one NO and two NC slow action contact, and is suitable for use in plant and building automation systems. The actuator provides 5 Newtons (N) of extraction force. The slow action "break-before-make” operation ensures the normally-closed (NC) contact opens before the normally-open (NO) contact closes, with the actuator forcibly opening the NC contacts for use in safety circuits. The two M20 x 1.5 mm electrical cable entries allow for threaded conduit connection. This mechanical limit switch conforms to the European Committee for Electrotechnical Standardization (CENELEC) EN 50047 standard for dimensions and mechanical data and the EN 50041 standard for quality assurance, and is suitable for use in interlock circuit applications.
