シリンダのピストン位置検知装置。 A permanent magnet attached around the piston in the fluid pressure cylinder is installed within a predetermined range within the detector body, which is attached to the outer circumferential surface of the cylinder tube made of non-magnetic material of the fluid pressure cylinder so that its mounting position can be changed. Then, the three detection elements that emit detection signals are moved in the direction of movement of the piston so that when the permanent magnet corresponds to the intermediate position between two adjacent detection elements, both of the detection elements emit detection signals. A piston position detection device for a fluid pressure cylinder, characterized in that indicator lights are arranged adjacent to each other and illuminated only when the detection element located in the center emits a detection signal.
