A sensor assembly that includes a sealed housing. A printed circuit board assembly including a first section that includes processing circuitry is disposed within the sealed housing and a second section that includes detection circuitry extends from the sealed housing. The sensor assembly also includes a conductive target movably coupled to the second section of the printed circuit board to vary net voltage of the detection circuitry as the conductive target moves along the second section to provide an output signal. The processing circuitry detects the output signal and converts the output signal into a linear representation of position of the conductive target in relation to the second section.
