Allen-Bradley 800T-QH10B Pilot Light

Allen-Bradley 800T-QH10B is a 30 mm pilot light in the 800T control component family, featuring a blue lens for clear visual indication in panel-mounted applications. It’s designed to be installed in control panels and machine enclosures to signal equipment status at a glance, serving as a compact visual cue in automation systems. The unit is rated for 120 V AC/DC operation, aligning with common industrial power standards, and sits within a product line that includes both LED and incandescent lamp variants. The 800T series is widely used for indicator signaling in manufacturing and packaging environments, and the blue lens variant provides a high-visibility indicator in crowded control panels or enclosures. Typical use cases include signaling machine readiness, fault indication, or process status in industrial automation, where a durable 30 mm indicator can be integrated with push-button assemblies or compact control stations.
