DESCRIPTION
A Ferroxdure FXD100 magnet mounted on the back of the sensor package provides an auxiliary field of 3.6 kA/m in the x-direction of the sensor. Typical applications for the KM110B/2 are current measurement, linear position measurement, rotational speed detection of magnetic pole wheels as well as magnetic field measurement.
