In one embodiment, a sensor circuit may include a first receiver circuit that may be configured to receive a first signal that is representative of a first mutual inductance and form a first detection signal that is representative of the first mutual inductance, wherein the first variable mutual inductance varies in response to a position of a metal object. An embodiment may include a second receiver circuit configured to receive a second signal that is representative of a second mutual inductance and form a second detection signal that is representative of the second mutual inductance, wherein the second mutual inductance varies in response to the position of the metal object. In an embodiment, the sensor circuit may include a recognition circuit configured to assert a movement detected signal responsively to a first value of the first detection signal, configured to assert a movement direction signal responsively to a first value of the second detection signal.
