The Schmersal AZM 161SK-12/12RK-024 is a bolting safety door interlock switch designed to guard access to industrial machinery, delivering a rugged, IP67-rated plastic housing with a large wiring compartment for straightforward field wiring. It features a 6-contact configuration (NC x4, NO x2), no-key operation with power-to-release and a manual release for emergency door opening, all housed in a compact enclosure sized 130 x 90 x 30 mm with four M16 x 1.5 cable entries for wiring to screw terminals. Electrical ratings include 24 V DC up to 2.5 A or 250 V AC up to 4 A, and the mechanism is rated for about 1,000,000 cycles with a locking force of roughly 2 kN, while the interlock provides protection against incorrect locking to prevent mis-engagement. The unit is double-insulated with a thermoplastic housing, designed for reliable operation in demanding environments where guard doors and access points must remain securely guarded and easily released in an emergency.
