Abstract:
An inductive position sensor determines a position of an object. The sensor incudes a circuit board, a wire source coil constructed and arranged to provide a certain operating frequency, a first wire sensing coil, and a second wire sensing coil. The source coil, and first and second sensing coils are embedded in the circuit board, and each of the first and second sensing coils are constructed and arranged to provide an output as the object passes by source coil and the first and second sensing coils. Eddy current generating material is associated with any of the coils so as to provide an eddy current that interferes with wire to wire communication between the sensing coils and the source coil, so as to alter the output of the sensing coils to improve accuracy of the sensor to shape the output.
