Siemens 3SE5112‑0LU22 Hinge Safety Switch, Metal Housing, IP67/IP69K, EN50041, 40 mm Width

1. Product Overview

The 3SE5112‑0LU22 belongs to Siemens SIRIUS 3SE5 series mechanical hinge safety position switch. It is specially used to monitor the open‑closed status of machine protective hinged doors and protective flaps. Adopts snap‑action positive‑opening contact structure. When the safety hinge door opens to 10° trigger angle, the switch will reliably cut‑off safety circuit, implement equipment safety stop function. Metal housing conforms to EN50041 standard, high‑grade IP protection, fit harsh industrial workshop environment.
