Rotary Potentiometers and Rheostats are electrical elements which are used to control the flow of the electrical current in a circuit, by varying the resistance value. The 91R1A-R22-B20L is one such element, used for a range of applications, due to its wide range of adjustability and reliability.

Rotary Potentiometers, or simply \'pots\' as they are often called, are a type of variable resistor which are predominantly used to control the voltage or current in a circuit. They consist of a circular or linear wiper contact which is connected to a resistive element. As the contact is rotated or moved along the element, it changes the resistance, resulting in a change in the current or voltage flowing through the circuit.

The 91R1A-R22-B20L is a type of linear rotary potentiometer, which is distinguished by its linear taper relationship. It features a 20-turn, which provides a much greater range of adjustment than a regular rotary potentiometer, making it much more reliable. The element consists of a resistive track which is segmented with uniform hashes, allowing for a very precise dial adjustment.

The 91R1A-R22-B20L is ideal for a broad range of applications, most commonly in devices such as audio equipment, amplifier and filter circuits, tuners, and other applications with a wide range of adjustability requirements. Due to its wide range of adjustment, they are also often used in a variety of other applications, such as testing and measurement, chemical analysis, signal conditioning, and motor control.

The working principle of a rotary potentiometer is quite simple. When the wiper contact is moved along the resistive element, the resistance value between the wiper contact and the two end terminals of the resistive element changes. This change causes a corresponding change in the current or voltage at the desired location in the circuit. This is known as ‘potentiometer action’, and it is this action which makes the 91R1A-R22-B20L so widely used in so many applications.

The 91R1A-R22-B20L is a highly reliable and versatile device, making it perfect for a wide variety of applications, from testing and measurement to motor control. Its wide range of adjustability and precision control make it ideal for situations where more precise adjustments are required, making it a great choice for anyone looking for a reliable and adjustable pot.
