It integrates ASIsafe communication via a fixed M12 plug (4-pole, pinout: ASI+ on pin 1, ASI- on pin 3) and provides positive opening switching — a mandatory feature for safety circuits in machine guarding applications per EN ISO 14119. The IP66/IP67 enclosure means the switch body and the M12 connection withstand high-pressure washdown and temporary submersion, making it suitable for food-and-bev lines, packaging cells, or outdoor conveyor systems where hygiene and moisture resistance are required. The 1300 N locking force holds the guard closed against forced entry or vibration — enough for heavy access doors on machining centers or press lines. The positive opening function mechanically forces the NC contacts open when the actuator leaves the switch head, regardless of welded contacts; this is the core safety principle for a category 4 / PL e circuit per EN ISO 13849-1. Repeat accuracy of 0.1 mm means the switch detects the same actuator position within a tenth of a millimeter cycle after cycle, critical for interlocking precision on high-speed tool changers. The ID1 code is set to F by default, configurable from 0 to F via the ASIsafe network, letting you address up to 16 switches on one AS-Interface segment without physical DIP switches. Mount in any position using screw fixing — the plastic enclosure is lightweight and corrosion-resistant. The M12 plug mates directly to an AS-Interface drop cable; no terminal wiring inside the switch, which saves panel-builder labor and reduces wiring errors. The switch accepts actuator approach from five directions, simplifying alignment on hinged or sliding guards. Mechanical service life is typical 1,000,000 operating cycles, so it outlasts most machine rebuild intervals. Vibration resistance to 0.35 mm / 5g and shock resistance to 30g / 11 ms keep it reliable on press brakes, stamping presses, and vibratory feeders.","metaTitle":"Siemens 3SF1324-1SB21-1BA3 Safety Position Switch, 1300 N Lo","metaDescription":"Siemens SIRIUS 3SF1324-1SB21-1BA3 safety position switch with tumbler, 1300 N locking force, IP66/IP67, positive opening, ASIsafe integrated.
