The Configuration of Roundss Rotary Encoder

     The encoder mainly by the code disc (circular grating, grating instructions), the body, the light emitting device, the photosensitive device and other components.

     (1) circular grating by the coating in light and dark stripes radially transparent material or material portrayed on the metal composition. A fringe spacing of adjacent gate section called a raster pulses (resolution) the entire circumference of the gate is the section number of the encoder. (Note: The company has three metal code wheel, glass, film (plastic-like) three).

     (2) index grating is a stationary, but the window stripe groove with circular groove identical grating grating sheet.

     (3) the body is assembled circular grating, indicating the carrier grating member.

     (4) The light emitting device is generally infrared LED.

     (5) high-frequency devices are sensitive photosensitive member; generally silicon photovoltaic cells and phototransistor.
