Unlike a potentiometer, the rotation count is unlimited. With the key on the rotary encoder, it can be reset to the initial state, that is, counting from 0. Working principle: Incremental encoder is a rotary sensor that converts rotational displacement into a series of digital pulse signals. These pulses are used to control angular displacement. The conversion of angular displacement in the Eltra encoder adopts the photoelectric scanning principle. The reading system is based on the rotation of a radial indexing disk (code disk) composed of alternating light transmitting windows and non light transmitting windows, while being vertically illuminated by an infrared light source, which projects the image of the code disk onto the surface of the receiver. The receiver is covered with a layer of diffraction gratings that have the same window width as the code disk. The job of the receiver is to sense the changes caused by the rotation of the optical disk, and then convert the light changes into corresponding electrical changes. "To raise the low-level signal to a higher level and generate a square pulse without any interference, electronic circuits must be used to process it.". The reading system usually adopts a differential method, which compares two different signals with the same waveform but with a phase difference of 180 °, in order to improve the quality and stability of the output signal. The reading is formed based on the difference between the two signals, thereby eliminating interference. Package include: 1pcs x 360 Degrees Rotary Encoder Module For Arduino </div></div>
