The cargo real object is accurate
Working voltage: 5V
A circle of pulses: 20
The rotary encoder can count the number of times of the output pulse during the rotation of the positive and opposite direction by rotating. The rotating count is not like a potential meter. This rotation count is not limited.With the buttons on the rotary encoder, you can reset to the initial state, that is0Start count.
working principle:
The incremental encoder is a rotating sensor that converts the rotary to a series of digital pulse signals.These pulses are used to control corner displacement.existEltraThe conversion of the angle shift in the encoder uses the principle of photoelectric scanning.The reading system is based on the rotation of the radial score disk (code disk) composed of alternate light transmittance windows and opaque windows.EssenceThe receiver covers a layer of diffraction grating, which has the same window width as the code disk.The job of the receiver is to feel the change generated by the disc ring of the disc, and then converts the change of light to the corresponding electrical change.Then increase the low level signal to a higher level and generate a square pulse without any interference, which must be processed with electronic circuits.The reading system usually uses differential methods.180°Different signals are compared to improve the quality and stability of the output signal.The reading is formed on the basis of the difference between the two signals, which eliminates interference.
