Schmersal 103039566 AZM 161CC-12/12KTU-024 – Solenoid Interlock with Escape Release, 24 V AC/DC
The Schmersal 103039566 (AZM 161CC-12/12KTU-024) is an electromechanical solenoid interlock from the Schmersal AZM 161 series. It keeps hinged, sliding and removable safety guards locked until hazardous machine movements have stopped.
- Power to unlock: the guard stays locked when the solenoid is de-energised. The guard locking function reaches up to PL e.
- Escape release: a red push button on the rear lets anyone trapped inside the guarded area open the guard from inside.
- Build: 2,000 N holding force, six contacts (four safety, two auxiliary) and a double-insulated IP67 thermoplastic enclosure.
