Where is the difference between the adjustable encoder and rotary encoder?

Rotary encoder is converting signals or data preparation, available in the form of communication, signal transmission and storage of equipment. Commonly used in car DVD, car navigation GPS, car audio, multimedia audio, instrumentation, medical equipment, household appliances, intelligent furniture, toys, machinery, equipment, etc. Contact output, using brush a brush contact conductive area or insulation area to represent the state of the code is the & # 39; 1 ' Or the & # 39; 0 ' ； Acceptance of non-contact sensor is photosensitive components or have a magnetic sensor, using photosensitive element to pervious to light and opaque to represent the state of the code is the & # 39; 1 ' Or the & # 39; 0 ' Through the & # 39; 1 ' And & # 39; 0 ' Collected the binary code to physical signal is converted into machine code can read the electrical signals to communications, transmission and storage of adjustable encoder is a kind of adjustable electronic components. It is formed by a resistor and a rotating or sliding system. When the resistance between two fixed electric shock, plus a voltage by rotating or sliding system change the location of the contact on the resistor body, between the fixed contact and moving contact can be a relationship with the moving contact position with a certain voltage, it is mostly used as a voltage divider. Encoder is basically a slide rheostat, there are several kinds of style, commonly used in speaker volume switch and laser power adjustment, such as size, the encoder is a kind of adjustable electronic components. It is formed by a resistor and a rotating or sliding system. When the resistance between two fixed electric shock, plus a voltage by rotating or sliding system change the location of the contact on the resistor body, between the fixed contact and moving contact can be a relationship with the moving contact position with a certain voltage. The role of adjustable encoder: adjusting voltage ( Including dc voltage and signal voltage) And the size of the current.
