    Abstract: A sensor module may include a back-bias magnet with a magnetization in a first direction. The sensor module may include a sensor chip including a first set of tunnel magnetoresistive (TMR) sensing elements. The sensor chip may be configured to determine a characteristic of a first magnetic field component using the first set of TMR sensing elements, and to generate a sensor signal based at least in part on the characteristic of the first magnetic field component. A value of the sensor signal may correspond to a linear position of a ferromagnetic object.
