Our Performance Series AZ/EL/AZ positioners represent the latest generation of multi-axis
rotary positioning subsystems.
They offer enhanced capabilities and improved performance relative to size and incorporate
new engineering advances.
This series provides accurate rotation, velocity, and direction for customers involved in antenna design
and development. Their rugged yet simple construction ensures maximum reliability and trouble-free
operation, yielding the best size and weight versus performance ratio.
Typically, the primary components include the body, precise slew bearings, DC motors, gear reducers,
synchro assemblies, and limit switch assemblies. The turntable surface is designed with a threaded
mounting hole pattern for customer use. A Safe/Operate switch is included to ensure the safety
of working personnel.

technical notes
1 All accuracy data is based on no-load conditions.
Contact ORBIT/FR for accuracy under load conditions.
2 All models are equipped with adjustable limit switches
capable of approx 20° to 900° total travel. When rotary
joint and slip ring options are specifi ed, limit switches
remain but are electrically disabled.
Multi-axis positioners are factory-set at:
• Upper Azimuth Axis: 400° (± 200°)
• Elevation Axis: 184° (± 92°)
• Lower Azimuth Axis: 400° (± 200°)
3 Slip Ring & Rotary Joint Option Notes:
• Certain slip ring options may require an extension
cap that protrudes above the turntable surface.
Positioner height may increase. Consult ORBIT/FR.
• Slip ring contacts for customer use are provided
with dedicated connectors.
• When rotary joint and/or slip ring options are
specifi ed, no central thru-hole is available to
the user. Option TH002-HD and TH003-HD
are available in lieu of rotary joint and/or slip ring
options.
4 AL-4588-1 and AL-4589-1 were previously listed as
AL-4578-1 and AL-4579-1, respectively. There is no
change in the specifi cations.
