Description

Pin type WH138-4 potentiometer with switch dimmer switch speed controller

Application:

Ideal for multimedia, computer speaker, stereos amplifier, lighting regulation etc.

Description:

Rorary potentiometer is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The position of the wiper determines the output voltage of the potentiometer. The potentiometer essentially functions as a variable voltage divider. The resistive element can be seen as two resistors in series(potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor.

A wide variety of potentiometers exist. Manually adjustable potentiometers can be divided into rotary or linear movement types. The tables below list the available types and their applications of rotary potentiometer:

Types Description Application
Single-turn potentiometer Single rotation of approximately 270 degrees or 3/4 of a full turn Most common potentiometer, used in applications where a single turn provides enough control resolution.
Multi-turn potentiometer Multiple rotations (mostly 5, 10 or 20), for increased precision. They are constructed either with a wiper that follows a spiral or helix form, or by using a worm-gear. Used where high precision and resolution is required. The worm-gear multi turn pots are often used as trimpots on PCB.
Dual-gang potentiometer Two potentiometer combined on the same shaft, enabling the parallel setting of two channels. Most common are single turn potentiometers with equal resistance and taper. More than two gangs are possible but not very common. Used in for example stereo audio volume control or other applications where 2 channels have to be adjusted in parallel.
Concentric potentiometer Dual potmeter, where the two potentiometers are individually adjusted by means of concentric shafts. Enables the use of two controls on one unit. Often encountered in (older) car radios, where the volume and tone controls are combined.
Servo potentiometer A motorized potmeter which can also be automatically adjusted by a servo motor. Used where manual and automatic adjustment is required. Often seen in audio equipment, where the remote-control can turn the volume control knob.

The taper of a potentiometer is normally indicated with a letter. The following table lists the used coding for potentiometer taper, different standards uses the same letters which can be confusing. It is always a good idea to double check the taper by measurement.
