This is one of the thinnest closed loop stepper motor we have, it only with 57.5mm thickness include encoder. The encoder is a magnetic encoder with 3 channels and 1000PPR(4000CPR) resolution. The biggest advantage for magnetic encoder is the size and cost, they are widely used in small space and higher cost performance.
