Abstract
A sensor, comprising: a supporting member; a permanent magnet that is coupled to the supporting member; and a sensor die having a plurality of sensing elements and processing circuitry formed thereon, the plurality of sensing elements being arranged to generate one or more signals in response to a pattern of magnetic flux density that is produced by the permanent magnet and modulated by an application of force to a shaft, the processing circuitry being configured to map the one or more signals to a value of a force applied to the shaft, and output an indication of the value of the force, wherein the permanent magnet and the sensor die are encapsulated in an encapsulating material, the encapsulating material being used to form a package of the sensor.
