Reading system of alternating light transmitting window and the window is not consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving on the surfacereceiver is covered with a diffraction grating, which has the same code disk window widthhow it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensorsthen the low-level signals up to a higher level, and generates no interference square pulse, which must be processed by electronic circuitsreading is then the difference between the two signals formed on the basis,thus eliminating the interferencein eltra angular displacement encoder conversion using a photoelectric scanning principleencoder ky-040 by rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which species rotation counts are not limitedthe receiver's job is to feel the rotation of the disc resulting changes, and change the light into corresponding electrical changesoperating voltage: 5v circle pulse count: 20with the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0these pulses are used to control angular displacementreading systems typically employ a differential manner, about the same but the phase difference of the two waveforms different by 180°compared to the signal in order to improve the quality and stability of the output signal
