The Siemens SIRIUS 3SF1314-1SJ11-1BA1 is a mechanical safety switch with a separate actuator and tumbler design, built for guard door monitoring on machinery where a positive-opening contact and a spring-actuated lock are required. The 2600 N locking force means the solenoid holds the guard closed against that much force before the latch gives way — critical for applications like rotating-drum access or press guarding where an operator must not defeat the interlock. Repeat accuracy of 0.1 mm ensures the switch position is consistent cycle after cycle, so you don't get nuisance trips from thermal expansion or wear over 1,000,000 typical switching cycles.
Deployment context and ratings
Rated IP65/IP67, so the metal enclosure with cathodic dip coating stands up to washdown in food processing or wet machining — the seal keeps coolant and dust out of the switch head. The M12 fixed connector (4-pole, AS-Interface pinout: Pin 1 = ASI+, Pin 3 = ASI-) simplifies wiring in a daisy-chained safety loop; no field-wiring the switch itself. Screw fixing to the machine frame is standard. The switch operates on 24 V for the magnet coil and carries an insulation voltage rating of 30 V with surge withstand of 0.8 kV — this keeps it within the AS-Interface system voltage limits. Vibration resistance per IEC 60068-2-6 is 0.35 mm / 5g; shock resistance per IEC 60068-2-27 is 30g / 11 ms — it stays latched through typical machine vibration and tool-change impacts.
Safety function and lifecycle
Mechanical service life is 1,000,000 switching cycles typical, which is standard for a solenoid-locked safety switch in moderate-duty applications. The ID1 code is set to F (default) with a range of 0 through F, configurable for AS-Interface addressing. Substance prohibitance date of 03/01/2017 indicates RoHS compliance alignment — the switch meets EU substance restrictions as of that date.
