    Allen Bradley Guardmaster 440G-LZ Guard-locking Interlock Switch


    Enhance the security of your machine guard and ensure maximum safety for your personnel with the 440G-LZ Solenoid Interlock Switch from Allen-Bradley Guardmaster. Expertly designed for use on partial body access guards, this switch keeps the safety barrier locked until the machine has come to complete stop, preventing access to hazardous areas. It has an excellent rated holding force of 1,300N, uses 60% less power compared to other guard locking switches due to its bi-stable solenoid and advanced algorithms, and can be used in a broad range of applications.

    The 440G-LZ uses advanced microprocessor technology with an RFID coded actuator for optimum reliability and efficiency. The RFID actuators can be selected as either standard or uniquely coded. When the safety switch locking bolt is extended into and detected by the actuator, two OSSD solid state outputs are enabled preventing the opening of the safety guard. The locking bolt will only attempt to extend when the correct actuator is detected and is continuously monitored for correct insertion within the actuator. This interlock device can be used as part of a guard locking safety system and is TÜV certified as meeting EN/ISO 13849-1 performance level ’e’ - the highest safety level for position and lock monitoring. The semiconductor OSSD safety outputs of the switch can be connected in series with other safety components that have OSSD solid-state outputs.

    Features and Benefits:


    • Available with Power to Lock (protection of machine production) or Power to Unlock (protection of people) functionality
    • Hygienic design and IP69K protection which ensures it is dust-tight and resistant to powerful jets of water, making it perfect for use in harsh wash down applications
    • Energy efficient green device that only uses 2.5 W
    • Compact design optimised for flexibility and ease of mounting
    • Diagnostic information provided by two highly visible 270° wrap-around LEDs
    • Supports both hinged and sliding guard doors with four directions of approach
    • Easy installation and handy QR code on the switch linking directly to the online user manual for rapid troubleshooting
    • Solid-state design and monitored outputs
    • Scalable protection against tampering with unique or standard coded RFID actuators
    • High holding force of 1,300 N (Fzh)
    • Solid-state OSSD outputs series connectable to EN/ISO 14119:2013
    • Features an auxiliary output as well as a manual release
