Rotary Potentiometers, Rheostats are a type of variable resistor used to regulate electrical current. They are also known as voltage dividers as they can measure unknown voltage by providing a known voltage in a circuit. The 81C1A-E28-A15L is a type of rotary potentiometer. It is used in many applications ranging from controlling the position of a valve to controlling the amount of current being drawn from a power supply. By using the appropriate control circuitry, these devices can be used to control the speed or intensity of anything from fans to lighting.

The 81C1A-E28-A15L is a three-terminal device that allows for both linear or logarithmic control. It consists of a rotating shaft connected to a contact wiper, which slides across a round resistive track connected between two of the terminals. One of the two remaining terminals is the common terminal while the other is the adjusted terminal. The type of device determines which terminal is assigned to which function. Depending on the application, either linear or logarithmic control can be achieved.

The rotary potentiometer is also known as a rheostat. To use this device, one supplies power to one terminal, usually the common terminal. The resistor track is connected to the other supply so that when the contact wiper is shifted across the track, it can divide the voltage and current appropriately. When the contact wiper is moved along the track, the current output is automatically adjusted. The key advantage of this device is that the voltage and/or current can be precisely adjusted, depending on the type of resistor track used.

The 81C1A-E28-A15L is a very versatile device with many practical applications. It has been used in a variety of different fields, including medical instrumentation, communications equipment, consumer electronics, and even industrial control systems. It is also a great choice for controlling the speed or intensity of light sources and motors. This type of device offers an easy and cost effective way to precisely regulate voltage and current levels, making it an invaluable tool. With its wide range of applications, it is easy to see why the 81C1A-E28-A15L is such a popular choice for controlling current and voltage.
