MS 20 SERIES

Open Linear Encoder with single-field scanning

  • Easy mounting as a result of large mounting tolerances
  • High insensitivity to contamination by use of an extensive Quasi-singlefield scanning principle
  • High traversing speed
  • Integrated subdividing electronics in the encoder head for up to times 100 interpolation (before quadrature)
  • "True" Reference Mark (accurate and repeatable from both traversing directions)
  • MS 20: Two independent switch signals (optical) for individual functions
  • MS 21: Position of Reference Mark can be selected by the customer
  • MS 21: One switch signal for special functions
