Rotary potentiometers and rheostats are two types of electrical components with similar functions and features, but slightly different mode of operations. Potentiometers are adjustable resistors with three terminals. The most common type of potentiometers are the multi-turn rotation types which have a shaft and a few turns of a resistor track. Rheostats, on the other hand, are also adjustable resistors but typically have two terminals instead of three.

The P091S-FC20BR10K is an adjustable, precision rotary potentiometer. It is used for various manually adjustable control applications, such as adjusting the level of a signal, voltage or current. It is designed for simple, accurate and convenient operation and reliability. The product features a highly accurate rotary mechanism and an extremely low contact resistance.

The rotary mechanism of the P091S-FC20BR10K is composed of a hollow cylindrical body with a spiral resistor track. The track has a total of 10 turns, and is divided into five 2-turn segments. The wiper is connected to a rotary mechanism which is connected to the knob, and turns along with the knob. When the knob is turned, the wiper moves along the resistor track, adjusting the voltage or current.

In operation, the resistance between the common terminal (the terminal to which one end of the resistor track is connected) and the wiper terminal (the terminal to which the other end of the resistor track is connected) changes linearly and continuously as the knob is turned. The resistance between the wiper terminal and the adjustable terminal (the third terminal connected to the mechanism) remains constant throughout the rotation.

The P091S-FC20BR10K is a high quality and reliable product, offering precise control over a wide range of values. It offers excellent stability and reliability in environments with wide temperature fluctuations. It is a compact, light-duty component which is easy to install and can be used in a variety of applications. Some typical applications include volume control, dimmer control, and frequency adjustment.
