Rotary Potentiometers, Rheostats

91A1A-B28-A18L is an example of a rotary potentiometer. Also known as rheostats or variable resistors, these components are used to control the flow of electricity in a circuit in a limited range, without having to build a completely new circuit. Such components work by allowing the user to adjust the flow of electricity through the circuit by changing the resistance in key points of the circuit.

These components typically have three pins. The two outer pins are the input pins, which provide the electrical current or voltage entering the device. The middle pin is the output pin, which provides the adjusted electrical current or voltage from the device. As the user turns the knob on the device, the resistance between the two input pins changes, thereby changing the level of electricity flowing through the circuit.

In circuits, 91A1A-B28-A18L is most commonly used in simple circuits as current control devices or volume control elements. For example, 91A1A-B28-A18L can be used to control the volume of a music player or amplifier, or to adjust the current in an electrical circuit. By changing the resistance between the two outer pins, the user can control the flow of electricity to the desired level.

Another application of 91A1A-B28-A18L is to dampen electrical signals in oscillator circuits. In this application, the device is used to adjust the frequency of the oscillations, or the amount of time the oscillations take to complete one period. By adjusting the resistance between the two outer pins, the user can adjust the frequency and dampening of the oscillations in the desired way.

A third application of 91A1A-B28-A18L is in instrumentation and feedback control systems. Such systems typically require a precise level of electrical current or voltage to function correctly. By using a device like 91A1A-B28-A18L, the user can precisely adjust the level of electrical current or voltage in the circuit, and thereby control the output of the system in a precise way.

These components are typically used in low-voltage applications, ranging from 4 to 24 volts. They are available in a range of sizes and shapes, and with a variety of output currents and resistances. Additionally, they are easily customizable, allowing users to create circuits that are tailored to their specific needs. Such components are an invaluable tool for any engineer or designer looking to control the flow of electricity in their circuits.
