Product description

Rotary encoder module
Working voltage: 5V
One ring pulse number: 20
Rotary encoder can count the number of times of output pulses in the direction of rotation and the opposite direction rotation by rotation. Rotational counting is not like potentiometer, this rotation counting is not limited. With the button on the rotary encoder, it can be reset to the initial state, that is, counting from 0.
Working principle:
An incremental encoder is a rotating sensor that converts rotation displacement into a series of digital pulse signals. These pulses are used to control angular displacement. The photoelectric scanning principle is used in the conversion of angular displacement in the Eltra encoder. The reading system is based on the rotation of the radial dial (Ma Pan), which is made up of an alternate transparent window and an opaque window. Meanwhile, it is irradiated vertically by an infrared light, and the image of Ma Pan is projected onto the receiver surface. The receiver covers a layer of diffraction gratings, which have the same window width as the code disk. The work of the receiver is to feel the change produced by the rotation of the disc, and then convert the light change into the corresponding electrical change. Then the low level signal is raised to the higher level, and the square pulse without any interference is produced, which must be processed by electronic circuit. The reading system usually uses differential mode to compare two different waveforms, but the phase difference is 180 degrees, so as to improve the quality and stability of the output signal. The readings are formed on the basis of the difference between the two signals, thus eliminating the interference.
Incremental encoder:
The incremental encoder gives two phase square waves, whose phase difference is 90 degrees, usually called the A channel and the B channel. One of the channels gives the information related to the speed, and at the
