LIA SERIES

Exposed Linear Encoder with Signal Control

  • Easy mounting as a result of large mounting tolerances
  • Insensitive to contamination due to dual optical sensors
  • High traversing speed
  • Integrated subdividing electronics in the encoder head or in the 15-pin D-sub connector
  • Up to times 100 interpolation (before quadrature)
  • "True" Reference Mark (accurate and repeatable from both traversing directions)
  • Dynamic Amplitude and Offset Control
  • LIA 22: Two independent optical end of travel switch signals
  • LIA 21: Position of Reference Mark selectable via switch signal
  • LIA 21: One switch signal for end of travel functions
  • SINGLEFLEX or DOUBLEFLEX steel scale tape option
