MS 25

Overview

  • Standard dimensions
  • System resolution: 2 µm - 0.1 µm
  • Display of the signal quality directly at the scanning head via 3-coloured LED function
  • Easy mounting without additional test box
  • Easy mounting as a result of large mounting tolerances
  • High insensitivity to contamination by use of an extensive singlefield scanning principle 
  • Interface: TTL, sinus 1 Vpp
  • Signal-immunity against aging and temperature changes
  • High permissible traversing speed 
  • Reference mark (accurate and repeatable from both traversing directions)
  • Integrated subdividing electronics in the encoder head: for up to times 200 interpolation (before quadrature)
  • Max. measuring length: 20 000 mm
  • Optional: two independent switch signals (optical) for individual functions
  • Optional: position of reference mark customizable
  • Optional: one switch signal for special functions

    Accessories

    • TMT 20 MK- Bandanbauhilfe

      TMT 25 MK tape mounting tool

      Enables a safe and precise mounting of a steel tape scale.

    • PWT 100 / PWT 101

      The PWT 100 / PWT 101 is a testing device for checking the function and adjustment of RSF Elektronik encoders. Thanks to its compact dimensions and robust design, the PWT 100 / PWT 101 is ideal for mobile use. A 4.3-inch touchscreen provides for display and operation. For example, for encoders with EnDat interface you can not only display the position value but also export the online diagnosis, shift datums, and perform further inspection functions.

      Available functions
      The performance range of the PWT 100 / PWT 101 can be expanded by firmware update. Appropriate firmware files that can be imported to the PWT 100 through a memory card (not included in delivery) will be made available at www.heidenhain.de.
