Professional OEM ROHS UL Carbon Film 16mm 10K 50K 500K Rotary Potentiometer With Rotary Big Current Dual Switch
Different types of potentiometers are used in our day to day life from the radio we listen to in the mornings to the television we watch at nights. These small but useful pieces can be used for comparing purposes, adjustments, and so on. In this article from Linquip, we want to talk about different POT types and each potentiometer application. Continue reading to know all about them.
From digital pot to rotary pot to linear pot, each and all these potentiometers have been designed for specific purposes. But before we get into the details, let’s quickly review what a potentiometer is.
Potentiometer (also known as POT) is a variable resistor that contains three terminals. This resistor has an adjustable voltage that you can manually change to control the electric current flow. It is all controlled with respect to Ohms Law. The potentiometer symbol is a rectangle or zigzag line that is placed between two linear lines. The most famous potentiometer application is in audio systems for changing the volume or other characteristics of audio signals.
Pots are made of resistive materials. They are made of carbon composition, conductive plastic, cermet, and metal film.
There are three main categories that potentiometers are classified into Linear Potentiometer, Rotary Potentiometer, and Digital Potentiometer. Each of them has been tailored for specific needs. But rotary POTs are the most commonly used potentiometer type.
This POT type is designed to deliver adjustable supply voltage to the circuits. Rotary potentiometers have been designed in a way that its rotary motion will be converted into varying resistance. Just like other common potentiometers, the rotary pot contains three terminals, two of them have uniform resistance and the middle terminal is connected to the resistance via a wiper (also known as sliding contact). This wiper is connected to a rotating knob for adjustment purposes. Movement of the knob will set the sliding contact in motion across the resistance. The result would be changing in the resistance of the POT.
Rotary potentiometers have different types themselves such as single-turn pot, multi-turn pot, concentric pot, dual-gang pot, and servo pot.
