Siemens 3SE5 112-0QV10 Safety Position Switch

Siemens 3SE5112-0QV10 is a SIRIUS safety position switch with a separate actuator designed for machine-guard door safety. Housed in a metal enclosure with a 40 mm DIN width for robust mounting, it provides slow-action contacts in a 1 normally open / 2 normally closed configuration and supports five directions of approach to fit diverse guard geometries. The device connection is 1x M20 x 1.5, enabling straightforward wiring to safety circuits. This base unit is designed to be used with the corresponding actuator 3SE5000-0AV0, which must be ordered separately to complete the safety mechanism. Typical applications include safeguarding protective doors on industrial equipment, where the switch helps ensure that the guard cannot be defeated and safety is maintained in stop/start circuits.
