とを特長とする、 位置検出センサの取付装置。[Claim for Utility Model Registration] A position detection sensor for hydraulic and pneumatic cylinders in which a magnetic scale is formed on the surface of the piston rod and a magnetic sensor is installed in the cylinder head for the magnetic scale, and a bearing is provided between the magnetic sensor and the piston rod. is provided so that the shoulder of the housing is pressed against the bearing to maintain a constant distance between the magnetic sensor and the surface of the piston rod to prevent the temperature of the sensor from rising due to heat generation due to sliding friction,
A gap is provided between the fitting of the inner diameter of the bearing and the outer diameter of the piston rod, and a gap larger than this gap is provided between the outer diameter of the bearing and the inner diameter of the head so that the outer diameter of the bearing does not interfere with the inner diameter of the head due to vibrations of the piston rod. A mounting device for a position detection sensor, which is characterized by being able to position the head hole.
