Patent ID: 7439735

Claim:
A non-contact position sensor comprising: a sensor assembly comprising a housing and at least one magnet disposed in said housing, said magnet disposed adjacent a magnetic field sensor disposed in said housing, said magnetic field sensor being spaced a fixed distance from said magnet and comprising a surface in opposed facing relationship to said magnet with a north-south axis of said magnet generally parallel to said surface, said sensor assembly mounted to a rail of an automobile seat rail system; and an activating member, said activating member being vertically spaced from a bottom surface of said housing; said magnetic field sensor providing a first output corresponding to a first amount of magnetic flux imparted perpendicularly to said surface of said magnetic field sensor when said activating member is in a first position relative to said sensor assembly, and a second output corresponding to a second amount of magnetic flux imparted perpendicularly to said surface of said magnetic field sensor when said activating member is in a second position relative to said sensor assembly, said first amount of magnetic flux being greater than said second amount of magnetic flux.
