Magnetic Rotary Click Board

The Magnetic Rotary Click Board™ is a very accurate position sensing board that utilises the HMC1512, a magnetic field displacement sensor IC. This integrated sensor uses two co-planar saturated-mode Wheatstone bridges which consist of four magneto-resistive elements per bridge. The precision of up to 0.05� in the angular range of �90� can be easily achieved using the Magnetic Rotary Click Board™, making it far more accurate than the commonly used Hall-effect sensors.
