Abstract
In an inductive sensor a ferrous core is provided and has generally opposed first and second ends. A winding assembly surrounds the core. First and second magnets are coupled to the first and second ends of the core and are oriented relative to one another so that like magnetic poles are opposing one another along a length defined by the core.
Claims16
An inductive sensor comprising:
- a ferrous core having generally opposed first and second ends;
- a winding assembly surrounding said ferrous core;
- and
- a first magnet coupled to said core at said first end and a second magnet coupled to said core at said second end, said first and second magnets being oriented relative to one another so that like magnet poles are opposing one another along a length defined by said core.

An inductive sensor comprising:
- a housing defining a bore extending therethrough;
- a ferrous core positioned in said bore;
- a bobbin extending around said core;
- said bobbin defining an exterior surface wrapped with copper wire;
- a pair of magnets each coupled to an end of said ferrous core;
- a conductor coupled to said ferrous core for transmitting signals indicative of changes in a magnetic field generated by said sensor;
- and wherein
- said pair of magnets is oriented relative to one another so that like magnet poles are opposing one another along a length defined by said core.
