Allen-Bradley 800T-QTH10R Push Button Pilot Lamp

Allen-Bradley 800T-QTH10R is a 30.5 mm LED pilot light in the 800T push-button family, designed for 120 V AC/DC operation. This red-indicator unit uses a red lens and includes one normally open contact, enabling it to function as both a visual status indicator and a simple control input in industrial panels. The compact 30.5 mm form factor fits standard 30 mm operator cutouts and provides bright, long-life LED illumination suitable for harsh environments. Typical applications include signaling machine status on control panels, feedback in Start/Stop circuits, and visual confirmation of active interlocks in manufacturing and process automation environments. As part of the 800T lineup, it shares the same mounting interfaces and electrical footprint with other 800T pilots, making it a straightforward replacement for older indicators where LED reliability and reduced maintenance matter.
