RV24YN 24mm metal shaft single turn carbon rotary potentiometer
Application:
The potentiometer can be worked as a voltage divider to obtain a manual adjustable output voltage at the slider from a fixed input voltage applied across the two ends of the potentiometer. The most common use of a rotary potentiometer is the volume-control pot.
Description:
The most common form of the potentiometer is the single turn rotary potentiometer. This type of potentiometer is often used in audio volume control (logarithmic taper) as well as many other applications. Different materials are used to construct potentiometers, including carbon composition, cermet, conductive plastic, and the metal film.
Rotary potentiometer (the most common type) vary their resistive value as a result of an angular movement. Rotating a knob or dial attached to the shaft causes the internal wiper to sweep around a curved resistive element.
Carbon rotary potentiometers are designed to be mounted onto the front panel of a case, enclosure or printed circuit board (PCB) using a ring nut and locking washer. They can also have one single resistive track or multiple tracks, known as a ganged potentiometer that all rotate together using one single shaft. For example, a dual-gang pot to adjust the left and right volume control of a radio or stereo amplifier at the same time. Some rotary pots include on-off switches.
