Allen-Bradley 440G-LZS21SPLA

The Rockwell Automation Allen-Bradley Guardmaster 440G-LZ guard locking safety switch is specifically engineered for safety applications, safeguarding operators and equipment by preventing unintended access to hazardous zones. With certifications for safety applications up to SIL 3 in line with IEC standards and Performance Level PLe Category 4 per ISO 13849-1, this switch is a crucial component in safety-related control systems. The 440G-LZ features OSSD outputs that are activated only when the locking bolt is securely sensed in position, confirming the guard is both closed and locked. It operates with a bi-stable solenoid and is meant for use with rigid guards, requiring a separately mounted latch and mechanical stop. Designed for reliability, the device ensures that stringent safety measures are consistently upheld in various industrial settings, making it an indispensable tool for maintaining a safe working environment.
