    Areas of application

    Precise speed and position monitoring for many different applications, for example:

    • Asynchronous motors
    • Machinery
    • Lift construction
    • Packaging systems
    • Textile and printing machines
    • Wind and solar power


    Key features
    • Reliable ShaftLock bearing design:
      Large, quality ball bearings with maximum distance prevent misalignment of the bearing assembly due to excessive axial shaft loading in operation or during installation.
    • Full shaft, hollow shaft that is open on one side or continuous
    • Massive aluminum die-cast housing with 1.5 mm wall thickness
    • All common output circuits
    • Product design unites form and function, making installation easier
    • Discreet optical integration into the application
    • Customer-specific persons on request
