The Siemens 3SF1314-1SH11-1BA1 is a SIRIUS-series mechanical safety switch with a tumbler mechanism, built for guard-door monitoring on machinery where a positive-opening contact is mandatory. It carries a 2 600 N locking force and accepts actuation from five directions of approach. The metal enclosure with cathodic dip coating and IP65/IP67 sealing suits washdown environments and heavy industrial use.
The 2 600 N locking force holds the guard closed against substantial force. The positive-opening function forces NC contacts open when the actuator is withdrawn, even if contacts have welded.
Integration and deployment
The switch integrates via a fixed M12 plug, 4-pole, with ASI+ on pin 1 and ASI- on pin 3. The AS-Interface slave profile is 7.B.F, meaning it carries ASIsafe safety communication directly on the ASI bus — no separate safety relay needed for the signaling path. The separate actuator 3SE5000-0AV0 must be ordered alongside. Screw fixing mounts it to the machine frame; mounting position is any orientation.
The lifecycle stage is current, so this remains an active catalog item from Siemens.
Shock resistance is 30 g / 11 ms per IEC 60068-2-27, vibration resistance 0.35 mm / 5 g per IEC 60068-2-6. The substance prohibitance date of 03/01/2017 aligns with RoHS compliance.
