Schmersal AZM 161SK-12 12RK-024 Safety Interlock Switch

Schmersal AZM 161SK-12/12RK-024 is a solenoid interlock switch designed to secure machine guarding and prevent access until a safe condition is verified. This unit is part of Schmersal’s AZM 161 family and features a large wiring compartment with four M16 x 1.5 cable entries, a manual release, and a thermoplastic, double-insulated enclosure that helps resist incorrect locking. Its compact body measures 130 mm x 90 mm x 30 mm and houses six electrical contacts for versatile safety wiring. The -024 variant uses a 24 V AC/DC coil for the power-to-unlock function and offers SPST-NO and SPST-NC configurations, making it suitable for safety circuits on guards for machines such as presses and conveyors. Built for long life in industrial environments, the interlock carries IP67 protection when mounted correctly, providing reliable performance in dusty or damp settings. This device combines rugged electromagnetic actuation with a robust mechanical design to ensure guarding integrity while enabling controlled access only after safety conditions are met.
