Rotary Potentiometers, Rheostats

Applied in many different areas, rotary potentiometers (or simply “pots”) are one type of variable resistor. As their name suggests, they are typically used to control the flow of current in electronic circuits where the magnitude of the resistance is varied. Rheostats, meanwhile, are resistors or devices capable of varying resistance. They are also often used as variable resistors, although not as widely used as potentiometers.

The 81C1A-E28-A20L is a type of rotary pot specifically designed to be used in an industrial environment. This pot has a robust design with a high degree of reliability, making it a great choice for applications that require precise control over voltage and current. It is largely similar to the classic rotary pot, except for its conductive construction, which optimizes the pot’s current control. The pot works by utilizing a small conductive track connected to a rotating shaft.

As the pot is being turned, the rotating shaft causes the track to move in a circular motion, and the rotational motion of the shaft is used to control the amount of current flowing through the track by changing the resistance. As the resistance is varied, the amount of current that flows through the track is also changed. This allows the user to adjust the amount of current passing through any given part of the circuit, enabling circuits to be more precisely tuned.

The 81C1A-E28-A20L pot is typically used in applications that require precision current control, such as industrial automation, power and energy management, and audio equipment. Its compact design makes it ideal for applications that require a low profile, such as HVAC control systems. Additionally, since it is constructed from robust materials, it is also suited to use in harsh environments.

The 81C1A-E28-A20L pot combines the accuracy of a potentiometer with the reliability of a rheostat. Its robust construction and wide range of operating temperature and voltage make it a great choice for applications that require precision current control. Its ability to finely tune the amount of current passing through any part of a circuit makes it an essential tool in many industrial applications.
