Allen-Bradley 800T-U29 30.5mm Potentiometer Unit

The Allen-Bradley 800T-U29 is a 30.5 mm potentiometer operator designed to be the adjustable input element within the 800T family of command devices, including pushbuttons and pilot-light assemblies, enabling precise, rotation-to-resistance feedback in industrial control panels. It employs a 10 kΩ resistive element with a linear taper, delivering proportional voltage division across its travel so operators translate user movement into predictable control signals for actuators, conveyors, machines, or process equipment, with robust mechanical compatibility for panel mounting. Electrical specifications place the unit for up to 300 V AC/DC operation and a power rating of 2.25 watts, with some catalogs listing a 2 W maximum; this range reflects variations across AB replacement data and vendor listings for the same model. The mounting diameter is 30.5 mm, and the part is referenced in AB literature as a replacement potentiometer unit for 800T installations (cross-reference 24752-221-12), confirming its role as a direct-fit, field-replaceable component within 800T control assemblies.
