The Schmersal AZ 16 ST2-AS R ASI-SAW safety switch is a two-channel, AS-Interface Safety at Work interlock with a separate actuator, designed for right-hand mounting and intended to monitor guard position in EN 60947-5-1 safety circuits. It comes in a plastic housing measuring 52 × 90 × 30 mm, rated IP67 for protection against dust and water, and features an M12 connector for robust field connections. Part number 101167263 and EAN 4030661218434 identify this model, which uses ASI‑SAW communication to feed guard status to an AS‑Interface master and is suitable for applications such as machine doors, safety gates, and other movable safety guards. To actuate the AZ 16 ST2-AS R, coded AZ 15/16 actuators are required, and the unit can be integrated with Schmersal ASM safety monitors on AS‑Interface networks to coordinate safe shutdown when the guard is opened.
