Product Description

1. Potentiometers come in many shapes and sizes. Look around in stores or on the Internet, and you should be able to find the perfect potentiometer for every need.
2. Some potentiometers are very small and can only be adjusted with a small screwdriver. This type of potentiometer is called a trimmer potentiometer and is designed to make occasional fine adjustments to circuits.
3. A switch is integrated in some potentiometers, so when you turn the knob all the way to one side or pull the knob out, the switch can turn the circuit on or off.
4. When the wiper reaches one end or the other of the resistor, the resistance between the center terminal and the terminals on that terminal is essentially zero. Keep this in mind when designing your circuit. To avoid circuit paths without resistors, a small resistor is usually placed in series with the potentiometer.

Resistor material classification
Carbon Film: Use a carbon film as a resistive film.
Metal Film: A special cermet film made of a mixture of ceramic and metal materials is used as a resistive film.
Wirewound: Use a metal wire wound as a resistor. Compared with carbon film or ceramic gold film, it can withstand higher power.
Tectonic classification
Rotary: The common form. The usual rotation angle is about 270 to 300 degrees.
Single-loop: The most common form.
Multi-turn type: used for occasions requiring precise adjustment.
Linear Slide: Often used in mixers to instantly see where the volume is and to do fade controls.
Quantity classification
Single type: One shaft only controls a single potentiometer.
Duplex: Two potentiometers are controlled by the same shaft, mainly used in two-channel, which can control two channels at the same time.
Resistance value change scale classification
Linear scale type: The change of resistance value is linearly related to the rotation angle or moving distance. This type of potentiometer is called a B-type potentiometer.
Logarithmic scale type: The change of resistance value is logarithmic with the rotation angle or moving distance. The main purpose of this type of potentiometer is volume control, among which the A-type potentiometer is commonly used, which is suitable for clockwise direction for high volume and counterclockwise direction For the occasion of low volume; In addition, there is another C-type potentiometer with the opposite direction of change of logarithmic scale.
Classified by the material of the resistor body
Potentiometers can be divided into two categories: wire-wound potentiometers and non-wire-wound potentiometers according to the material of the resistor body. Wire-wound potentiometers can be divided into general-purpose wire-wound potentiometers, precision wire-wound potentiometers, high-power wire-wound potentiometers, and pre-adjusted wire-wound potentiometers. Non-wire wound potentiometers can be divided into two types: solid potentiometers and membrane potentiometers. The solid potentiometer is divided into organic synthetic solid potentiometer, inorganic synthetic solid potentiometer and conductive plastic potentiometer. Membrane potentiometers are further divided into carbon film potentiometers and metal film potentiometers [1].
Sort by adjustment
Potentiometers can be divided into rotary potentiometers, push-pull potentiometers, and slide-type potentiometers according to the adjustment method [1].
Classification according to the change law of resistance value
Potentiometers can be divided into linear potentiometers, exponential potentiometers and logarithmic potentiometers according to the changing law of resistance value [1].
Classification by structural characteristics
Potentiometers can be divided into single-turn potentiometers, multi-turn potentiometers, single-joint potentiometers, double-joint potentiometers, multi-joint potentiometers, tap potentiometers, switch potentiometers, locking potentiometers, There are many kinds of non-locking potentiometers and chip potentiometers [1].
Sort by drive
Potentiometers can be divided into manual adjustment potentiometers and electric adjustment potentiometers according to the driving method [1].
Other special types
With switch potentiometer: It is usually used to combine the volume switch with the power switch, that is, turn it counterclockwise to the end to cut off the switch and turn off the power.
