Product Description

Digital rotary encoder module Rotary potentiometer Rotary  potentiometer without knob cap         

Working voltage: 5V

Pulses per revolution: 20

The rotary encoder can count the number of pulses output during the forward and reverse rotation by rotating. The rotation count is not like a potentiometer. There is no limit to this rotation count. With the key on the rotary encoder, it can be reset to the initial state, that is, counting from 0.


working principle:

An incremental encoder is a rotary sensor that converts a rotary 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 uses the principle of photoelectric scanning. The reading system is based on the rotation of a radial indexing disk (code disk) consisting of alternating light-transmitting windows and opaque windows. At the same time, it is vertically illuminated by an infrared light source. The light projects the image of the code disk onto the surface of the receiver. . The receiver is covered with a layer of diffraction grating, which has the same window width as the code disc. The receiver's job is to sense the changes caused by the rotation of the disc, and then convert the light changes into corresponding electrical changes. The low-level signal is then raised to a higher level, and a square pulse without any interference is generated, which must be handled by electronic circuits. The reading system usually adopts the differential method, that is, two different signals with the same waveform but a phase difference of 180 ° are compared to improve the quality and stability of the output signal. The reading is based on the difference between the two signals, eliminating interference.
