Thumbwheel Potentiometers are used to measure angular displacement and control the output voltage or current of a system. They are similar to traditional potentiometers in that a mechanical element measures the change in electrical resistance and the device produces a corresponding output voltage or current.

The most common form of thumbwheel potentiometers is the EVU-TW1B24A13, a digital thumbwheel potentiometer used in a variety of applications. The EVU-TW1B24A13 is electrically similar to a conventional resistor and consists of up to 24 measured elements, each element representing one data bit. This thumbwheel potentiometer is commonly used in televisions, computers, and other electronic gear.

The EVU-TW1B24A13 thumbwheel potentiometer functions as an analog to digital converter. The operation of the thumbwheel potentiometer is based on a value table of the electrical resistance and corresponding voltage readings. The first thumbwheel is divided into 24 sections, each having a measured resistance value and corresponding voltage value. Electrical signals corresponding to the voltages are generated and fed into a on-chip analog-to-digital converter, which outputs the corresponding digital signal. The voltage values are converted to digital equivalents, which are then used to control the output of the system.

The EVU-TW1B24A13 thumbwheel potentiometer is found in a variety of applications, primarily in consumer electronics such as television receivers, VCRs, and remote control units. It is also used in automotive and HVAC applications. Its primary advantage over other potentiometer designs is its ability to provide high accuracy and resolution for low cost. The thumbwheel design also minimizes wear and tear on the potentiometer, resulting in a longer operational life and greater reliability.

The EVU-TW1B24A13 thumbwheel potentiometer is a specialized form of rotary potentiometer that can be used to control the output of a system. It operates by measuring the incremental change in electrical resistance in 24 measured sections and outputting the corresponding voltage values. This design is particularly suited for use in consumer electronics, as it provides high accuracy and resolution for low cost.
