  "abstract": "This disclosure describes a guarding interlock system employing a coded magnetic sensor and a defeat-resistant mounting arrangement. The system addresses the common problem of guard defeat due to operational inconvenience, which can lead to hazardous conditions. By utilizing a unique magnetic code and a mounting method that integrates the sensor and actuator into the guard structure, the system ensures that the guard’s closed position is reliably detected while making unauthorized bypass attempts difficult and detectable. Furthermore, features are incorporated to facilitate routine access without compromising safety integrity, thereby improving usability and reducing motivation for defeat.",
