Its 1 300 N locking force holds the guard closed against process forces or machine vibration, and the positive-opening switching function ensures the NC contacts break mechanically even if welded — a critical safety feature for PL d / SIL 2 applications. The 1 300 N locking force secures heavy or pneumatically loaded guard doors where a standard 1 000 N switch would risk release under pressure. Repeat accuracy of 0.1 mm detects actuator misalignment before the guard is fully closed.","metaTitle":"3SF1324-1SF21-1BA1 SIRIUS Safety Switch, 1300 N Locking, IP6","metaDescription":"Siemens SIRIUS 3SF1324-1SF21-1BA1 mechanical safety switch with tumbler, 1300 N locking force, IP65/IP67, M12 AS-Interface.
