  • Displacement encoder, device comprising such an encoder and method of manufacturing such an encoder
    Patent number: 7633289
    Abstract: Displacement encoder for a moving shaft, having a sleeve intended to be clamped on the shaft and an encoding zone having polarized magnetic mark. The encoding zone has permanent magnet disposed against the sleeve and a layer of elastomer is overmolded and adherized on the magnet and on the sleeve.
    Type: Grant
    Filed: September 6, 2005
    Date of Patent: December 15, 2009
    Assignee: Hutchinson
    Inventors: Patrick Fayaud, Laurent Guerbe
  • Encoder for a movable shaft, a device including such an encoder, and a method of fabricating such an encoder
    Patent number: 7385388
    Abstract: An encoder comprising a sleeve for holding on a shaft and an encoder element secured to the sleeve. The encoder element presents an encoding zone that is protected by a thin layer of material deposited by plasma directly on the encoder element and secured thereto, the thin layer covering at least the encoding zone A device including the encoder and a method of fabricating the encoder are described.
