It integrates ASIsafe communication via a fixed M12 plug (4-pole, pinout: Pin 1 = ASI+, Pin 3 = ASI-), so it reports both actuator and magnet status directly onto the AS-Interface bus without a separate safety relay. The 1 300 N locking force (verified per EN ISO 14119 at 1 000 N) means this switch holds a hinged or sliding guard door against forced opening — suitable for heavy access panels on machine tools or conveyor cells where an operator could lean against the door. Repeat accuracy of 0.1 mm ensures the actuator position is detected consistently cycle after cycle, critical for maintaining the safety distance calculation in a light-curtain-free zone. IP65/IP67 protection means the plastic enclosure withstands washdown from hoses and temporary immersion — deployable in food processing or wet machining areas without an additional cover. The switch accepts actuation from 5 directions of approach, giving panel builders flexibility to mount it on any side of a guard frame without custom brackets. Compliance documentation covers RoHS substance prohibitance dated 03/01/2017. The switch carries an AS-Interface slave profile of 7.B.F and is designed per EN ISO 14119 with positive opening operation. ## Integration notes Mounts in any position via screw fixing. The M12 connector is fixed (not field-wirable), so pre-terminated cables or a field-attachable M12 connector are needed. The 24 V magnet coil draws its supply from the AS-Interface bus; no separate power feed required. Environmental limits: operate from -25 to +60 °C, store from -40 to +80 °C. Shock resistance is 30g / 11 ms; vibration resistance is 0.35 mm / 5g per IEC 60068-2-6 and IEC 60068-2-27.","metaTitle":"Siemens 3SF1324-1SJ21-1BA1 Safety Switch, 1300 N Locking For","metaDescription":"Siemens SIRIUS 3SF1324-1SJ21-1BA1 safety position switch with tumbler. 1300 N locking force, IP65/IP67, ASIsafe integrated, 24 V magnet.
