Abstract
A magnetic sensor module includes an axially polarized back-bias magnet having a body that radially extends from a magnet center axis and a bore extending along the magnet center axis. The magnet generates a radial bias magnetic field about a magnetization axis in a sensor plane. The magnetic field has a magnetic flux density of substantially zero along a perimeter of a zero-field closed loop located in the sensor plane. The magnetic sensor module includes a shim polepiece mechanically coupled to an end of the axially polarized back-bias magnet. The shim polepiece includes a second bore centered on a polepiece center axis that is aligned with the magnet center axis. The second bore extends through the shim polepiece along the polepiece center axis.
