に構成したことを特徴とする直線位置検出器。 Hall elements are placed at symmetrical positions on both sides of the axis of a magnetic body that moves in the axial direction in conjunction with the object, and magnetic elements are placed at symmetrical positions on both sides of the axis offset by 90 degrees with respect to the Hall element. At the same time, either the Hall element or the magnet element is arranged along the axial direction of the magnetic body so as to sandwich the other element, and when the magnetic body is moved in the axial direction, detection by the Hall element is performed. A linear position detector characterized in that the voltage can be extracted differentially.
