Allen-Bradley 800MR-PT16G Pilot Light

Allen-Bradley 800MR-PT16G is a 22.5 mm round pilot light with an integrated transformer and a push-to-test control, designed to operate on 120 V AC (50/60 Hz) in industrial control panels. It uses a green lens indicator and incandescent lamp and includes stab-terminal connections for quick, reliable wiring in field installations. The 'PT' designation identifies this unit as the Push-To-Test variant within the 800MR family, offering a convenient way to confirm lamp function and transformer operation with a single pushbutton. This model is part of Rockwell Automation's 800MR pilot-light lineup and is commonly used as a status indicator in machinery and control enclosures, where a compact, 22.5 mm format is required for panel space efficiency.
