The SIEMENS 3SE5112-0CE01 is a position switch in a 40 mm metal enclosure designed to meet EN 50041 mounting standards, providing reliable limit detection for industrial machinery. It offers one normally open and one normally closed quick-action contact for clear switching states, with a single device cable entry (M20 x 1.5) for straightforward installation. The actuator combines a metal lever and a 22 mm plastic roller to handle repeated mechanical contact while reducing wear. This compact switch is suited for conveyor stops, guards, or machine axes where accurate position sensing and simple wiring are required.
