The use of incremental encoder！

An incremental encoder is a sensor that outputs the measured angular displacement in pulses. The code disc is in the 360 ° circle subdivided a number of equal parts lines, the more lines, the higher the resolution. General incremental encoder has three code channels, that is, A, B, Z Road. A, B phase difference of 90 °, for judging the direction of rotation; Z phase for incremental encoder to record the number of turns.
     Incremental photoelectric encoder mainly by the light source, code disc, detection grating, photoelectric detection devices and conversion circuit. The invention is characterized in that an output pulse signal corresponding to an incremental displacement is capable of generating a pulse electrical signal equivalent to a displacement increment, and the electric signal is displayed or controlled by a host instrument or a computer to control the attitude of the object to be measured.
    Incremental encoder is mainly used to measure the speed, acceleration, rotation direction, angle and so on. Widely used in walking machinery, CNC machine tools, elevators, servo motors, flow meters, textile machinery, metallurgical machinery, injection molding machinery, printing and packaging machinery, automated instrumentation and other industrial automation monitoring and control.
