Rotary Potentiometers and Rheostats are both types of variable resistors, consisting of a stationary, resistive element and a rotating contact called a wiper. Although the applications and working principles of the two components are similar, their designs differ significantly.

First, let’s discuss Rotary Potentiometers. These consist of a tubular element with a metal or plastic spindle, usually with a plastic or metal bottom, which contacts the rotating element to provide a signal which varies in proportion to the angular movement. A resistance element is inside the tube, and as the spindle is turned, the output resistance value changes. Depending on the device, this output can be a DC voltage or resistance. Rotary Potentiometers are widely used for functions such as volume and tone control in electrical items such as sound equipment, amplifier, and other electronic control systems.

The second type of variable resistor is known as a Rheostat. Sometimes called a potentiometer, these consist of a resistive element in the form of a resistive wire loop, or wiper, which moves along a resistive track layer. Depending on the application, they also have a resistance element, which will change as the wiper rotates along the track. A rheostat is typically used for controlling electrical currents in circuits, including controlling power to electrical devices such as relays, transformers, solenoids, and motors. They can also be used as an adjustable potentiometer for controlling the intensity of light in lamps and other lighting fixtures.

Now, let’s take a look at the specific example of a “P232-SFC25BR10K” component, which is a type of rotary potentiometer. This device uses a ceramic body with an epoxy-dipped cover and an aluminum bottom which contacts the rotating element to provide a signal which varies in proportion to anglular movement. The resistance element of the P232-SFC25BR10K is a multi-turn wire wound potentiometer, with a 10K ohm resistance range. It is designed for use in a wide variety of electronic control systems, including sound equipment, amplifiers, home automation systems, and industrial process control systems. In addition to providing an adjustable signal, this potentiometer is also able to conduct AC and DC signal levels by connecting to appropriate cables.

Rotary Potentiometers and Rheostats are two essential types of variable resistors with similar applications but different designs. The P232-SFC25BR10K is an example of a rotary potentiometer which has a 10K ohm resistance range and is designed for use in electronic control systems. It is able to conduct both AC and DC signals, and can be used for a variety of tasks including volume and tone control, light intensity control, and motor/relay/transformer/solenoid control.
