Allen-Bradley 800T-U35 Rotary Potentiometer 20k Ohm

Allen-Bradley 800T-U35 is a 30 mm rotary potentiometer unit designed to function as the internal potentiometer element of Rockwell Automation’s Bulletin 800T operator stations, translating shaft rotation into a linear resistance change with a 20 kΩ value for predictable, repeatable response. The device is specified with a linear taper and a power rating of 2.25 watts, making it suitable for panel-mounted analog adjustments where a compact, rugged potentiometer is required within the 800T series’ push-button assemblies. For ordering and replacement, it is cataloged as 24752-221-14, confirming compatibility with 800T-U35 assemblies and the broader 800T 30 mm potentiometer family, and it is the standard internal potentiometer component specified for the 800T-U35 configuration. In practice, technicians use the 800T-U35 to calibrate or trim analog control parameters in industrial automation panels, enabling precise adjustments for process setpoints or machine control signals without replacing the entire operator interface.
