Schmersal AZM 161SK-12 12RKA-024 Safety Interlock

Schmersal AZM 161SK-12/12RKA-024 is a solenoid interlock with power-to-lock operation that uses a 24 V AC/DC coil to secure a machine guard while hazards are present. It comes in a 130 × 90 × 30 mm thermoplastic, IP67‑rated enclosure with a large wiring compartment and four M16 × 1.5 cable entries, and it provides six contacts (four safety contacts plus two auxiliary contacts) to support the safety circuit. It is designed for protection against incorrect locking, includes a manual release, and offers long service life, making it suitable for guarding doors on machinery where lock integrity must be maintained under power and released via the control system.
