Magnetic Rotary Encoder (2012)

pcbmagencoder

 

I designed a small evaluation PCB for the AS5040 magnetic rotary encoder chip from ams.  This chip allows detection of the rotary position of a magnet with 10 bits of resolution, or approximately 0.35 degrees.  This chip enables a lot of possible applications for non-contact shaft feedback such as fluid-moving pumps, wear-less speed sensors, etc.
