Manufacturer 9mm Horizontal Type Rotary Potentiometer Dual Gang
Potentiometer For Audio Application
Product Description:
A rotating potentiometer is a tunable resistor that slides over the
resistor by a brush and obtains an output voltage related to the
input voltage in the circuit. Mainly used in communication
products, walkie-talkies, automotive power amplifier, multimedia
audio, smart home, computer peripherals and so on.
Features of Rotary Potentiometer
- Using plastic sealing structure, can effectively deal with wave
welding.
- Good sealing performance meet IP65 standard.
- Have 1,11,21,41 detents options.
- Push-pull switch or rotating switch options.
- Shaft length and shape can be customized.
- A variety of mounting methods for choice.
Application of Rotary Potentiometer
Rotary potentiometer is mainly suitable for communication products,
walkie-talkies, multimedia audio, automotive power amplifier and
other electronic equipment, can also be used in household
appliances, medical equipment, its main functions are: volume
adjustment, light emphasis section, menu selection, speed
adjustment, temperature adjustment, etc.
