Product Description
We can manufacture:
Rotary Potentiometer
The most common type of potentiometer where the wiper moves along a circular path.
Type | Description | Applications |
Single-turn pot | Single rotation of approximately 270 degrees or 3/4 of a full turn | Most common pot, used in applications where a single turn provides enough control resolution. |
Multi-turn pot | 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 pot | 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 pot | 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 pot | 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. |
Linear potentiometers
Potentiometers where the wiper moves along a linear path. Also known as slider, slide pot or fader.
Type | Description | Applications |
Slide pot | Single linear slider potentiometer, for audio applications also known as a fader. High quality faders are often constructed from conductive plastic. | For single channel control or measurement of distance. |
Dual-slide pot | Dual slide potentiometer, single slider controlling two potentiometers in parallel. | Often used for stereo control in professional audio or other applications where dual parallel channels are controlled. |
Multi-turn slide | Constructed from a spindle which actuates a linear potentiometer wiper. Multiple rotations (mostly 5, 10 or 20), for increased precision. | Used where high precision and resolution is required. The multi turn linear pots are used as trimpots on PCB, but not as common as the worm-gear trimmer potentiometer. |
Motorized fader | Fader which can be automatically adjusted by a servo motor. | Used where manual and automatic adjustment is required. Common in studio audio mixers, where the servo faders can be automatically moved to a saved configuration. |
