Allen-Bradley 800H-UR29 Rotary Potentiometer

Allen-Bradley 800H-UR29 Rotary Potentiometer is a 30.5 mm frame potentiometer designed for use with the 800H family of operator interfaces. It features a 10 kΩ resistive element (30.5 mm FS, 10 kΩ), enabling precise resistance-based position sensing within control panels and pilot devices. The UR29 model is specified as a potentiometer unit within the 800H catalog, intended for integration with 800H operator interface components to add adjustable sensing capabilities to a control station. This unit aligns with Allen-Bradley’s standard 800H accessories, providing a consistent interface for modular control panels and simplifying wiring when upgrading legacy equipment. Common applications include process automation and machine tooling where manual adjustments or calibration of a control variable are required directly at the control station, such as threshold setting, calibration routines, or trim adjustments in conjunction with 800H equipment. By selecting the 800H-UR29, maintenance and automation professionals can preserve a consistent 800H interface while adding precise rotary sensing, enhancing panel integration and ensuring compatibility with existing Allen-Bradley hardware.
