TRANSDUCER

A transducer for a position sensor is described. The transducer comprises a single laminate sensor board carrying a plurality of windings formed by conductors on one or more layers of the sensor board, the windings being arrayed over a first area of the sensor board; and detection circuitry mounted on another layer of the sensor board over a second area of the circuit board and electrically coupled to said windings, said detection circuitry having a first mode of operation in which signals inductively coupled to or from said windings are detected and a second mode of operation in which signals capacitively coupled to or from said windings are detected. The windings and detection circuitry are arranged on the sensor board so that said first and second areas oppose each other. A position sensor incorporating the transducer is also described.
