OPERATING VOLTAGE: 5V

LAP NUMBER OF PULSES: 20

By rotating the rotary encoder may be counted positive and reverse directions during the rotation frequency of the output pulse, the rotation count unlike potentiometer, this rotation count is not limited. With buttons on the rotary encoder can be reset to the initial state, that starts counting from 0.

HOW IT WORKS:

The incremental encoder is a rotational displacement is converted to a series of digital pulse signals rotary sensor. These pulses are used to control the angular displacement. In Eltra angular displacement encoder using a photoelectric conversion scanning principle. Reading system to rotate the radial indexing plate (code disk) by alternating opaque and translucent windows windows constitute the basis, while the vertical irradiation by an infrared light source, the light of the code disk image projected onto the surface of the receiver . The receiver is covered with a layer of a diffraction grating, which has the same width of the window code disk. The receiver's job is to feel the changes generated by rotation of the optical disk, and then converted into corresponding electrical light variable changes. So that a low level signal again rises to a higher level, and generates no interference of square pulses, which must be processed by electronic circuits. Reading systems typically employ differential mode, but is about the same as the two waveforms phase of 180 ° for the different signals is compared, in order to improve the quality and stability of the output signal. The difference between the two readings is then formed on the basis of the signal, thereby eliminating the interference.
