PRODUCT DESCRIPTION
ALLEN BRADLEY 440F-C28026 - Safety Light Curtain
This device is a GuardShield 440F series compact safety light curtain engineered for point-of-operation and perimeter guarding in industrial environments. It provides personnel protection by establishing an optical barrier, detecting intrusions into hazardous areas, and activating machine stop functions via solid-state OSSD outputs. Designed for integration with safety relays or programmable safety controllers, it ensures compliance with machine safety directives in applications such as robotic work cells, automated assembly lines, and material handling systems.
