Allen-Bradley 800EM-LG9 Pushbutton Operator Illuminated

Allen-Bradley 800EM-LG9 is an illuminated guarded pushbutton operator in the 800E/800F family, built for panel-mount control in industrial equipment. Designed for a 22.5 mm mounting diameter, it fits standard 22 mm control-panel cutouts for quick replacement or retrofits. The LG9 designation identifies an illuminated guarded actuator, providing a visible status indicator when energized and a physical barrier to reduce accidental actuation in busy or harsh environments. This 22 mm pushbutton is commonly employed for basic control tasks such as start/stop, selection, or function switching within automation lines, packaging equipment, conveyors, and machine tools, where reliable operator input and clear visual feedback are essential. As part of Allen-Bradley’s legacy 800E/800F platform, the 800EM-LG9 is designed to integrate with compatible controllers and interlocks that share the same mounting footprint and electrical interface, enabling straightforward installation and consistent control cabinet ergonomics across devices.
