Inductive sensor for piston detection

Sheet No.: 6-401 GB


  • Mounting directly in oil port
  • Detecting end position of piston
  • Housing and detector unit is designed to separate without spillage of oil, if mechanical distortion should occur
  • Low build-in height
  • The top can turn 355° around. Therefore it is possible to choose the optimal output angle for the connector
  • Plug and play solution
  • Reliable in all environments
  • Increased operation safety
  • Extremely precise detection
  • Longer durability
  • Less downtime
  • No adjustment
  • Easy cable-leading
  • Replaceable at once by crew
  • More safety on board
