Incremental optical rotary encoders with 1000 ppr can be used for robots, workbenches, injection molding machines, electronic equipment, printing and packaging machinery, non-standard equipment and CNC machine, a variety of office automation systems, industrial automation control and measurement fields.
Tips: The resolution of the incremental encoder The resolution of an optical incremental encoder is expressed in terms of the number of basic cycles of the output signal generated by the encoder shaft rotating a circle, namely the number of pulse per revolution (PPR). The number of light-transmitting slits on the code disc is equal to the resolution of the coder. The more the slits engraved on the code disc, the higher the resolution of the coder. In the industrial electric drive, depending on different application object, usually choose optical incremental encoder with 500-6000PPR resolution, or up to tens of thousands of PPR. AC servo motor control system is usually selected with a resolution of 2500PPR encoder. In addition, if the photoelectric conversion signal is logical processed, the pulse signal with 2 times or 4 times of the frequency will be get, and the resolution will be further improved.
