MI-54050 Positioner newcolor

The MI-54000 Family of Elevation-over-Azimuth Positioners permits the rotation of elevation at fixed positions of azimuth. The MI-54000 Family of Elevation-over-Azimuth Positioners is assembled in the (standard) eccentric configuration. All except the MI-54050 can easily be converted to the concentric configuration during installation.

  • Permits rotation of elevation axis at fixed azimuth positions
  • Rugged construction assures superior reliability and longevity
