  • Magnetic stroke sensor for detecting the stroke of a fluid-power cylinder
    Patent number: 4839591
    Abstract: A method for easy and accurate positioning of a magnetic sensor in a fluid-power cylinder facing a magnetic scale on the lateral surface of a piston rod, wherein the sensor is supported by a hole in the cylinder, a piece of friction-resistant, non-magnetic material attached to the sensor projects from its detection surface towards the piston rod, and the non-magnetic material is made to keep in touch with the lateral surface of the moving piston rod by a pressure-applying bias. The friction-resistant, non-magnetic material is either fitted to the magnetic detection surface, or is formed into a tubular shape and fitted to the outer circumference of the sensor.
