ABSTRACT:
A non-contacting position sensor detects relative displacement between two objects. A magnetic flux source is provided by a plurality of discrete magnets selectively determined to produce a highly configurable flux source that is easily adapted to rotary or rectilinear displacement. The interaction of the individual flux fields generated by the discrete magnets is controlled to produce both linear and non-linear relationships with respect to changes in displacement. A flux-gathering pole piece is dimensionally optimized to integrate the plurality of individual flux fields directed to a magnetic sensor.
