Abstract: Provided herein are improved magnetic sensor systems for use in linear measurement systems. A magnetic sensor can be positioned offset from a center line positioned between two magnets. The two magnets can be oriented so as to provide opposite polarities. As the magnetic sensor traverses a path parallel to the magnets and parallel to the center line, the sensor can detect a magnetic flux density provided by the two magnets. Offsetting the magnetic sensor from the center line can improve the linear range of the magnetic sensor, thereby improving the reliability and accuracy of an output signal generated by the magnetic sensor based on the detected magnetic flux density.
