RV90X Rotary Potentiometer For Professional Audio System
Description of Rotary Potentiometer
The rotating potentiometer is an adjustable electrical resistor, which slides on the resistors by the brush, and obtains the output voltage associated with the input voltage in the circuit. It is mainly used for communication products, walkie-talkie, automobile power amplifier, multimedia audio, smart home, computer peripheral, etc.
Features of Rotary Potentiometer
Using plastic sealing structure, can effectively deal with wave welding.
Good sealing performance
Push-pull switch or rotating switch can be chosen.
Shaft length and shape can be adjusted.
A variety of mounting methods for choice.
