Rotary Potentiometers, Rheostats are widely used as a part of electronic circuits and systems, providing an adjustable resistance in a variety of applications. This article will discuss the application field and working principle of 81A2A-B28-A10/A10L Rotary Potentiometers, Rheostats.

A rotary potentiometer works as a voltage divider, with a shaft or paddle connected to a resistive element, a type of atom. As the shaft rotates, a sliding contact called a wiper sweeps around the resistive element to reach at different position. This changes the resulting resistance of the element, thus varying the voltage or current passed through. An example could be an electronic volume control; as the knob is turned, the resistance of the atom changes, changing the available voltage and ultimately, the output audio volume.

The 81A2A-B28-A10/A10L series are continuous rotation versions of a rotary potentiometer, making them an excellent choice for applications such as robotic arms, solar panels, or any other device that requires continous control of a variable. The 81A2A-B28-A10/A10L series are a very popular option as they provide a high degree of accuracy when controlling the voltage level as well as ideal shaft rotation speeds. They are also designed for high reliability and durability, making them a preferred combination for precision industrial and medical applications.

81A2A-B28-A10/A10L Rotary Potentiometers, Rheostats are solid state devices that are composed of two basic components; the resistor and the wiper. The resistor is usually composed of a metal film that is deposited onto a base material and is patterned into a specific shape in order to create a resistive material. The second component is the wiper which is also composed of a metal, usually a copper or a gold alloy, and is attached to a shaft that rotates in order to control the position of the wiper on the resistor. The device works similar to audio volume control on a radio, where the position of the wiper determines the resistance between the ends of the resistor.

81A2A-B28-A10/A10L series come in a variety of wiper and resistor packages that are designed for various applications. These include both panel mount and through-hole designs, as well as various mounting styles that range from embedded PCB mounting to surface mount. Designs are also available with extended life ranging from 10 million to 20 million rotations, and are ideal for applications in harsh environments.

The 81A2A-B28-A10/A10L series of Rotary Potentiometers, Rheostats are useful for a variety of applications, including precision motor control, user interfaces, and control systems. They are designed to provide a precise, consistent, and reliable resistance output throughout the full rotation range, and are an ideal choice for precision industrial and medical applications. The high accuracy and reliability of the 81A2A-B28-A10/A10L series of Rotary Potentiometers, Rheostats make them a cost-effective solution for a variety of important applications.
