Incremental Magnetic Encoder
Magnetic encoder is mainly including a magnet and a PCB which could read the magnet N and S poles. And then the sensing parts could tell the rotational position information in the form of signal output. Magnetic encoder has the advantages of anti-shock, reliable performance, simple construction. Incremental magnetic encoder is with lower cost than optical encoder. Optical encoder 's resolution depends on the lines on glass disc. The bigger disc, the more lines, the higher resolution. Magnetic incremental encoder can be in high resolution with small size.
