Allen-Bradley 800T-QTH2R Indicator Light

Allen-Bradley 800T-QTH2R is a 30.5 mm red LED indicator light built into a Push-To-Test 800T pilot-light unit designed for panel mounting in industrial control environments. The metal-bodied unit operates on 12–130 V AC or DC and features a dual-contact configuration: 1 normally open (NO) and 1 normally closed (NC), enabling straightforward signaling alongside status indication. With a 30.5 mm footprint and Type 4/13 enclosure protection, it is suited for demanding applications where visibility and reliability are essential in harsh or washdown-prone settings. The red LED illumination provides clear visual feedback in congested control panels, and the QTH2R variant is commonly used to augment 800T/800H pushbutton assemblies in machines and automation cabinets, offering a robust, testable indicator for operator interfaces and process signaling.
