Schmersal 103004166 AZM 161CC-12/03KA-024 – Solenoid Interlock, 24 V AC/DC
The Schmersal 103004166 (AZM 161CC-12/03KA-024) is an electromechanical solenoid interlock from the Schmersal AZM 161 series. It locks hinged, sliding and removable safety guards until hazardous machine movements have stopped.
Key characteristics:
- Power to lock: the guard is locked only while the solenoid is energised.
- Holding force: 2,000 N (FZh to EN ISO 14119).
- Six contacts: five safety contacts and one auxiliary contact.
- Enclosure: double-insulated, glass-fibre reinforced thermoplastic, IP67.
- Wiring: large wiring compartment with four M16 cable entries.
