Safety switch with integrated AS-Interface and 2600 N locking force
The Siemens 3SF1314-1SD11-1BA1 is a SIRIUS safety position switch with a tumbler mechanism, designed for guard door monitoring in safety circuits. It delivers a locking force of 2600 N per EN ISO 14119, meaning the actuator holds the guard closed against forced opening up to that force threshold. The switch integrates AS-Interface safety (ASIsafe) on a fixed M12 connector, with pin 1 for ASI+, pin 3 for ASI-, and pins 2 and 4 unassigned. The magnet coil operates at 24 V DC/AC. Repeat accuracy is 0.1 mm, and the mechanical service life is typically 1,000,000 operating cycles.
IP66/IP67 enclosure for washdown environments
Rated IP66/IP67, the metal housing with cathodic dip coating withstands high-pressure washdown and temporary submersion. This makes the switch suitable for food-and-beverage lines, washdown zones, and outdoor installations where moisture or debris ingress is a concern. The enclosure is metal, and the switch head material is also metal. Mounting position is any, with screw fixing.
