The Rockwell Automation Allen-Bradley Guardmaster 440G-LZ is a guard locking safety switch designed for use in safety applications. It is a critical component of a safety-related control system, ensuring the safety of operators and equipment by preventing accidental access to hazardous areas. The device is certified for use in safety applications up to and including SIL 3 according to IEC 61508 and IEC 62061, and Performance Level PLe Category 4 in compliance with ISO 13849-1.
Technical Specifications
The 440G-LZ features OSSD outputs that are enabled only when the locking bolt is sensed in its extended position in the actuator, indicating that the guard is both closed and locked. The locking bolt drive mechanism uses a bi-stable solenoid. The device is designed for use on guards that are engineered to be rigid without sag and requires a separately mounted latch (for example, magnetic, mechanical) and mechanical stop.
