Schmersal AZ 16 ST2-AS RB USNT Safety Interlock

Schmersal AZ 16 ST2-AS RB ASI-SAW safety interlock is a compact electromechanical locking device designed for guarded safety doors, where the guard must be closed to enable machine operation. This AZ 16 ST2-AS variant with a separate actuator (R) and AS-Interface Safety at Work (ASI-SAW) offers integrated diagnostics and safe status signaling through the AS-I bus. The exact configuration for this model is Art.-Nr. 101167263, confirming a right-hand (RB) mounting variant in the AZ 16 family. The interlock is housed in a plastic enclosure measuring 52 × 90 × 30 mm, rated IP67 for protection against dust and water ingress, and wired via an M12 connector for robust field connections in industrial environments. Applications include guarding doors on presses, forming, conveyors, and packaging lines where rapid-access maintenance is required without compromising safety. Its separate actuator design supports modular installation and alignment with standard door hardware, helping ensure reliable actuation and locking in demanding manufacturing settings.
