Abstract / Hauptanspruch
A sensor circuit is configured for operation under conditions susceptible to misalignment or movement. In connection with various example embodiments, an alignment-tolerant sensor arrangement includes a reference component and first and second magnetic sensors. The reference component influences a magnetic field as a function of a position of the reference component, such as via the positioning of a magnetic type of component. The first magnetic sensor is aligned with a first magnetic field sensitivity direction, and exhibits an electrical response to the presence of the magnetic field. The second magnetic sensor is aligned with a first magnetic field sensitivity direction and is configured to exhibit an electrical response to the presence of the magnetic field. The first and second magnetic field sensitivity directions being offset from one another to facilitate detection of magnetic fields at different relative alignments between the reference component and the first and second magnetic sensors.
