Schmersal AZM 161SK-12 12RKAT-024 Safety Switch

The Schmersal AZM 161SK-12/12RKAT-024 is a bolting solenoid-interlock safety switch with a power-to-lock action, designed to secure access doors on industrial machinery. It operates on a 24 V coil (24 V AC/DC) and comes in a plastic IP67-rated housing, enabling reliable use in harsh environments and easy bolt-on installation. The safety mechanism provides a multi-contact arrangement with NC x4 and NO x2 contacts, supporting robust monitoring of door status and interlock condition within safety circuits. Part of the AZM 161 family, the RKAT-024 suffix identifies the 24 V coil variant, tailored for safety applications that require locking the door when power is applied and unlocking when de-energized. Common applications include guarding access to hazardous zones on presses, conveyors, and robotic work cells, where a lockable door and verifiable interlock state are essential for maintaining safe operation.
