PRODUCT DESCRIPTION
ALLEN BRADLEY 442G-MABASHFT - GuardShield Safety Light Curtain
The ALLEN BRADLEY GuardShield 442G series provides optical personnel protection for industrial machinery by establishing a configurable safety barrier. These Type 4 safety light curtains utilize advanced optical sensing technology to detect intrusions into hazardous areas, initiating a safe stop command to connected control systems. Engineered for integration into safety circuits, they are suitable for applications requiring robust point-of-operation or perimeter guarding, including robotic work cells, automated assembly lines, and material handling systems, ensuring compliance with international safety standards. The suffix MABASHFT does not correspond to standard configuration options for the 442G series therefore, specific parameters tied to this suffix cannot be decoded. General specifications for the GuardShield 442G series are provided.
