Rotary Potentiometers

A rotary potentiometer is a type of electrical component which varies resistance when a knob on its face is turned. The resistance changes in a linear fashion across the entire range of rotation. Potentiometers are used widely as a voltage divider for analog signals, and as user interfaces for physical control of equipment such as electronic devices and laboratory instruments. The most common type of rotary potentiometer, the single-turn variety, is limited to a total range of one full rotation.

The CU2531E is one of the most advanced rotary potentiometers available on the market. It has a long-life and low-noise design, which makes it ideal for a variety of applications. Its full-range rotation of 360° provides smooth, consistent resistance change over its entire operating range. It also features a wide variety of turn angles and formats, which give the user the ability to customize the component for specific applications.

The working principle of the CU2531E is simple but elegant. As the shaft is rotated, the contact wiper moves on the resistive element. This causes the resistance value between the two terminals to vary, creating an adjustable voltage divider. By shifting the contact position, the current output of the component can be changed accordingly. As a result, the component can be used as a user interface for controlling a variety of devices.

Rheostats

Rheostats are similar in action to rotary potentiometers, but are designed with a rotary action to provide variable resistance control instead of variable voltage control. Like potentiometers, they feature a resistance-track element, a contact wiper, and two fixed contacts. However, instead of a knob that the user holds and turns, rheostats feature a shaft-like movement that provides more precise and incremental resistance adjustment. The most common type of rheostat on the market is the wire-wound, single-turn variety.

The CU2531E is a high-precision, single-turn wire-wound rheostat. It is designed for high accuracy and reliable operation over a full-range rotation of 360°. It also features a range of turn angles and formats, allowing users to customize the component to their specific needs.

The working principle for the CU2531E is similar to that of a potentiometer. As the contact wiper moves across the resistive element, resistance is changed accordingly. This adjustment causes the voltage across the two terminals to change, producing a varying current to whatever device is connected to it. In this way, it can be used to adjust the current or voltage in a device, allowing the user to customize the device for various applications.
