Allen-Bradley 800T-QMH24R Pilot Light

Allen-Bradley 800T-QMH24R Pilot Light is a 30 mm red indicator device in the 800T family, designed to mount in standard 30 mm pushbutton assemblies and provide a compact, high-visibility status cue on industrial control panels. It operates at 24V AC/DC and delivers steady red illumination to signal power presence, machine readiness, or fault conditions, a common setup for line-start indicators and process monitoring in manufacturing environments. The QMH designation denotes a modular, panel-mount pilot-light format that integrates with other 800T components, allowing technicians to replace or upgrade indicators without re-wiring and ensuring consistent panel compatibility across Rockwell Automation installations. In practical use, this pilot light supports quick status checks in applications such as packaging lines, assembly stations, and automation controls, where a clear, immediate visual signal helps operators and maintenance staff respond promptly to changing conditions.
