91A1A-B28-A13L

The 91A1A-B28-A13L is a rotary potentiometer, a type of variable resistor. It is also known as a rheostat, because it functions in a similar way to a standard rheostat. A rotary potentiometer differs from a rheostat in the way it is designed and the way it works. A rotary potentiometer has a circular, round shape with a central axis of rotation. The rotating part of the potentiometer is called the spindle. At the end of the spindle is a small metal disk with two or more contact points. The rotating disk is connected to a wiper that moves along the resistance track as the spindle is turned. The resistive element is usually a carbon element.

The 91A1A-B28-A13L is designed to provide adjustable resistance within a certain range. The resistance can be adjusted by turning the spindle, which moves the wiper along the resistance track. This allows the potentiometer to adjust the voltage or current that is applied to a device or circuit by adjusting the resistance. This makes the potentiometer very useful in a wide variety of applications, such as adjustable power supplies, sound level controllers, volume and tone controls, and motor speed controls.

Rotary potentiometers are used in a wide variety of electronic circuits and devices. They are used in audio systems to adjust the volume and tone of speakers and other audio components. They are also used in power supplies to adjust the output voltage and current. They can be used in motor speed controls to adjust the speed of electric motors. Another important use for rotary potentiometers is in light dimming systems, where the amount of light produced by a light source can be adjusted.

Rotary potentiometers are relatively simple devices, and they are easy to use. They consist of a few basic components: a resistive element, a spindle, and a wiper. The resistive element is usually a carbon track, although other resistive materials may be used as well. The spindle is a rotating shaft that is connected to the wiper via a small metal disk. When the spindle is turned, the wiper moves up or down the resistance track, adjusting the resistance and thus the voltage or current applied to the device or circuit.

The 91A1A-B28-A13L is a versatile and reliable rotary potentiometer. It is designed for use in a wide variety of applications, from audio systems to motor speed controls. It is a simple device to use, and it is relatively inexpensive compared to some other types of adjustable resistors. For these reasons, the 91A1A-B28-A13L is a popular choice for many projects, and it is widely used in a variety of industries.
