Thumbwheel Potentiometers are potentiometers used for various applications such as audio, video, and measurement feedback. They are often found in consumer electronic devices such as CD players, cassette players, VCRs, and television receivers. Thumbwheel potentiometers are commonly used to adjust sound volume, brightness, and other parameters in an audio/visual system.The 91AR2KLF Thumbwheel Potentiometer is a type of rotary potentiometer designed specifically for audio and video equipment. This potentiometer is constructed with an outer rotating cylindrical shaft and an inner stationary wiper. The outer shaft has a groove or track that the wiper arm follows as the shaft is turned. It is typically constructed with a shaft that can be rotated and can be adjusted by a finger, thumb, or screwdriver. As the shaft turns, the resistance value of the potentiometer changes due to the contact of the wiper with the conductive track surfaces.The 91AR2KLF Thumbwheel Potentiometer is ideal for applications requiring frequent adjustments. It is ideal for applications that require a high level of accuracy, such as audio and video equipment, as it provides superior precision and repeatability when positioned. The 91AR2KLF Thumbwheel Potentiometer provides a wide range of adjustment from 0 ohms to 18.3k ohms in 1/2 watt or 0 ohms to 22.7k ohms in 1 watt rating.The 91AR2KLF is constructed of a durable and corrosion resistant epoxy resin case, an injection molded sealed plastic cover, and an epoxy resin end cap. The potentiometer is rated for 1 watt and continuous operation, with 0.1% accuracy at DC 10 V. This makes it ideal for applications requiring a high level of accuracy, such as audio and video equipment, as it provides superior precision and repeatability when positioned.The working principle of the 91AR2KLF Thumbwheel Potentiometer can be explained in terms of its connection type. It consists of two connection types, namely 2-wire and 3-wire. In the 2-wire connection, the wiper is connected to one end of the track and the ground is connected to the other end. This design provides a linear voltage output when the potentiometer is adjusted. On the other hand, in the 3-wire connection, the wiper is connected between two resistance paths, and the ground is connected to one end of each path. This design provides a non-linear voltage output when the potentiometer is adjusted.The 91AR2KLF Thumbwheel Potentiometer is ideal for audio, video, and measurement feedback applications. It is ruggedly constructed, providing accurate and repeatable adjustments and superior performance in the most demanding environments. It offers a wide range of adjustment from 0 to 18.3k ohms in 1/2 watt and 0 to 22.7k ohms in 1 watt rating providing high accuracy and precision.The specific data is subject to PDF, and the above content is for reference
