Thumbwheel potentiometers do not require complex control systems or intricate panels to set their resistance. With a few turns of the thumbwheel, the user can precisely set resistance to the desired level, making them ideal for designs that require a high degree of accuracy. Potentiometer technology has made considerable technical advances in recent decades, and one example of this is the 91AR20LF. This component benefits from a range of attributes, which make it suitable for use in a variety of applications. In this article, we’ll discuss the 91AR20LF’s application field and working principle.

The 91AR20LF is designed to work in the temperature range of -20° to 70°C. This makes it suitable for use in industrial, medical, automotive, and consumer electronics applications. It features a smaller package size (7mm x 5mm) compared to most standard potentiometers, allowing for more compact designs. This makes the 91AR2OLF ideal for applications where space is at a premium. It features a digital encoding feature, which delivers high precision and functionality. Additionally, the device is able to perform linear or switchable functions and comes with two decimal points.

As for its working principle, the 91AR2OLF comprises of three terminals which are connected to three resistors. These resistors are jointed in a line. The potentiometer\'s main terminal is connected to a third wiper whose position is controlled by the thumbwheel. When the thumbwheel is turned, the wiper can move across the resistors and the resistance between the two end terminals increases or decreases accordingly. This resistance is continuously adjustable, allowing for precise control.

The 91AR2OLF is able to offer high accuracy and reliability. Its push-on feature prevents accidental rotation of the thumbwheel, ensuring that the desired settings are not interrupted during operation. It also has a linearity tolerance of just ±3%. This allows the 91AR2OLF to achieve a high resolution rate. Other features of the 91AR2OLF include low temperature drift, high stability, and fast response time. It is also capable of handling up to 200V DC.

The 91AR2OLF is a versatile component that is suitable for a broad range of applications. Its small size and high precision make it an ideal solution for medical, industrial, automotive, and consumer electronics designs. Furthermore, its fast response time, low temperature drift, and excellent stability mean that it is a reliable and accurate solution. As such, it is an excellent choice for designs that require a high degree of accuracy and precise control.
