Rotary Potentiometers, Rheostats

The 91U1A-T22-B20L is a type of rotary potentiometer (trimmer), a device that uses a wheel or knob to adjust the resistance of a circuit. It is commonly referred to as a trimmer because its resistance value, or "tolerance," can be adjusted through the use of a turning knob or wheel. Unlike a common potentiometer, a trimmer has a much smaller adjustment range and does not require a tool for adjustment. The 91U1A-T22-B20L is designed to increase or decrease its resistance by turning the adjusting knob.

Application field

The 91U1A-T22-B20L is most commonly used in audio and video equipment as well as industrial controls, robotics, and test equipment. It is also commonly used in manufacturing to adjust the flow of electricity, like in car circuit boards, temperature controllers, and other electronic devices. This type of potentiometer is used to adjust and control the voltage or current of an electric circuit. Crucially, the 91U1A-T22-B20L can be used to precisely control and monitor a circuit, providing a reliable and accurate method of controlling a wide range of electronic devices.

Working principle

The 91U1A-T22-B20L is an adjustable component used to increase or decrease the resistance of an electrical circuit. It consists of a resistive element, a rotatory control knob, and a connecting pathway. The resistive element uses a resistive material to change the resistance value of the circuit when the knob is adjusted. The knob is connected to a shaft on the rotary control, and when rotated, the dial adjusts the resistance value. The connecting path bridges the gap between the resistive element and the knob. When the knob is turned, the resistive element adjusts the resistance, allowing the electrical circuit to control the flow of electricity more accurately.

The 91U1A-T22-B20L is a highly reliable and accurate device. It is designed to be easy to use and manipulate, allowing for a wide range of precise and adjustable values. As a result, it is an invaluable component used in a wide variety of electronics, from audio and video equipment to test and industrial equipment.
