MSS 25

Overview

Modular Angle Encoders MSS 25 without integral bearing are used as position and rotator control for electrical drives and in the measurement technology.

  • Measuring range: <360°
  • Grating period: 40 µm
  • Accuracy of the grating (even state, not bent): ±15 µm/m
  • Grating carrier: steel tape scale with adhesive tape

Accessories

  • Anbauhilfe für MSR 20

    Mounting aid MH MSS 25

    Mounting aid for the scanning head of MSS 25 (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.
