Allen-Bradley 800MR-QT24R Small Round Pilot Light

Allen-Bradley 800MR-QT24R is a 22.5 mm round, incandescent pilot light designed for 24 V AC/DC operation within 800MR modular push-button assemblies. The QT designation denotes Push-To-Test functionality, enabling quick lamp verification by pressing the actuator rather than energizing the external circuit. This full-voltage indicator features a red lens and ships without a contact cartridge, with mounting compatibility that supports stab terminals or no-termination configurations depending on the panel hardware. Ideal for panel-mounted status indication in industrial control panels, motor controllers, and automation enclosures where a compact, reliable 24 V indicator is required. Pairing with the appropriate 800MR contact blocks yields a complete control-station solution, while preserving a small 22.5 mm footprint for dense panel layouts.
