Abstract: Magnets are arranged at intervals along a stroke direction with an interposed space. Magnetic pole surfaces of adjacent ones of the magnets have opposite poles. A detector is arranged with a gap in a gap direction against a magnetic pole surface of each of the magnets and acquires a sine signal and a cosine signal as detection signals of phases corresponding to the positions of the magnets, based on a change in a magnetic field received from the magnets according to movement of the detector relative to the detection object in the stroke direction. A signal processor acquires the sine signal and the cosine signal from the detector, generates, based on the sine signal and the cosine signal, an arctangent signal corresponding to a stroke amount of the detection object relative to the detector, and acquires the arctangent signal as a position signal.
