Abstract
A linear position sensor assembly includes a moving target and a stationary magnet. A magnetic sensor is placed adjacent to the magnet and senses changes in the magnetic flux density caused by the target moving within a magnetic field generated by the stationary magnet. The magnetic sensor outputs a signal that is linear over nearly the entire length of the target.
