MSS 15

Overview

Incremental modular angle encoders MSS 15 without integral bearing are used as position and rotator control for electrical drives and in the measurement technology.

  • Online signal stabilization
  • Display of the signal quality directly at the scanning head via 3-coloured LED function
  • Permanent control of the signals over the whole measuring range
  • High quality of the signals due to singlefield scanning

    Accessories

    • Mounting aid MH MSR 15

      Mounting aid for the scanning head of MSR 15 und MSS 15 (diameter-dependent).

    • 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.
