Rotary Potentiometers

Rotary potentiometers are commonly used in applications which require precise handwheel rotation, such as instrument control, speed or power control, or position indication. The potentiometer is comprised of a shaft, a spool, a lever and a ceramic core. When the shaft is turned, the lever moves within a slot cut into the spool and tracks the position of the core accurately.

The resistance of a rotary potentiometer increases as the spool is rotated, which is why it is also referred to as a rotary rheostat. The resistance can be determined from the number of turns the shaft has been rotated, allowing precise handwheel rotation to occur.

Working Principle:

When the shaft of a rotary potentiometer is turned, the lever moves within a slot cut into the spool and tracks the position of the core accurately. As the core is moved, the gap between it and the lever changes, increasing or decreasing the resistance. The resistance of a rotary potentiometer is proportional to the amount of rotation, so it can be used to measure displacement and/or speed.

The resistance of the rotary potentiometer also reflects the position of the spool, allowing it to be used as a level or a position indicator on machines, such as lathes, milling machines or CNC machines. The resistance can be easily adjusted using a control wheel or button.
