Rotary encoder is widely used in communication products intercom, car amplifiers, multimedia audio, intelligent household and so on electronic field, has the volume, the light intensity adjustment, menu selection, speed adjustment, temperature control, and so on, and how these effects play out? What is the role of the rotary encoder? The role of the rotary encoder were summed up as three points: a, control current: when the current output is sliding contact terminal, the rotary encoder can be used to control current. Second, the partial pressure, which is assigned to the part of the voltage, when the encoder sliding bean or turn the handle to adjust when moving contact sliding. With the output of the encoder can obtain encoder and the voltage and the trip into a certain relationship of output voltage. Three, change resistance: connect both ends when the encoder device, the encoder within the scope of the stroke can obtain a smooth continuous variation of resistance, the encoder is to have the effect of the change of resistance. Shanghai electronic 26 years specializing in the production of rotary encoder, the encoder model is complete, safe and reliable quality, advanced production and testing equipment, trustworthy, looking for a rotary encoder manufacturer is looking for electronic.
