Rotary Potentiometers, Rheostats: 91A2A-B24-B20/B20L application field and working principle

Rotary Potentiometers and Rheostats are electrical resistors used to control the amount of electric current flowing through a circuit. The 91A2A-B24-B20/B20L is a type of rotary potentiometer and rheostat manufactured by the Amphenol Corporation..

The 91A2A-B24-B20/B20L offers 3 possible voltages, either 24, 20, or 20L, and provides a wide range of electrical resistance values from 0.1 ohms to 500 ohms. The 91A2A-B24-B20/B20L is a 10-turn potentiometer that can be used for a range of applications such as controlling the amount of current flowing through a circuit, adjusting sound levels on an audio system, or adjusting the brightness of an LED. It can also be used as a rheostat to vary the amount of current flowing through a circuit.

The 91A2A-B24-B20/B20L is a three-way rotary potentiometer which means that it has three separate resistance networks that can be used separately or in combination. The three resistors that are used are the wiper, rheostat, and the resistor. The wiper is the main component that is responsible for providing the electrical resistance of the potentiometer. The rheostat is used to vary the current flowing through the potentiometer while the resistor is used to set the maximum resistance.

The 91A2A-B24-B20/B20L can be used in a variety of applications in both industrial and consumer electronics. They can be used in audio systems to control the amount of current flowing through the system, in LED lighting systems to adjust the brightness of LEDs, in motors to control the speed of motors, and in home electronics to adjust the sound levels or voltage levels of different components.

The working principle behind the 91A2A-B24-B20/B20L rotary potentiometer is relatively simple. When the shaft is rotated, it turns a mechanical wiper across multiple resistors. This wiper makes contact with a certain number of resistors, depending on the position of the shaft. Depending on the number of resistors the wiper is making contact with, the amount of current flowing through the potentiometer is varied. This is how the 91A2A-B24-B20/B20L is able to adjust the voltage or sound level of a circuit.

The 91A2A-B24-B20/B20L is an ideal choice for a variety of applications thanks to its wide range of available voltage and resistances. Its versatility and easy installation make it an excellent choice for both novice and experienced electronics designers and hobbyists. As long as the user has the proper knowledge and tools to install the 91A2A-B24-B20/B20L, they should be able to use it for a variety of different applications.
