Schmersal 101212250 AZM 161CC-12/12RKA-024G – Solenoid Interlock with LEDs, 24 V AC/DC
The Schmersal 101212250 (AZM 161CC-12/12RKA-024G) is an electromechanical solenoid interlock from the Schmersal AZM 161 series. It keeps hinged, sliding and removable guards locked during critical machine or process steps.
This version works on the power-to-lock principle: the guard is locked only while the solenoid is energised. Three status LEDs show door closed, solenoid on and door locked at a glance.
Other key characteristics:
- 2,000 N holding force
- increased latching force of 30 N
- six contacts: four safety contacts and two auxiliary contacts
- double-insulated IP67 thermoplastic enclosure
