Series 500 Linear Position Transducer

Benefits

  • Non-Contact - No wear, such as found with pot wipers on conductive mylar, particularly when mounted on dithered actuators or vibrating installations
  • Low Power Needs - Allows use with printed circuit-level supplies of +5 Vdc
  • No Drift - No periodic re-calibration needed
  • Customizable Active Zones - Offers full output sensitivity for smaller active zones
  • Customizable Reading Direction - Forward or Reverse acting analog output allows match to control requirements
  • Only available with parallel motor mount and certain stroke lengths
