technical notes
� 1 All accuracy data is based on no-load conditions.
Contact ORBIT/FR for accuracy under load conditions.
� 2 AL-4368-1 and larger 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:
Azimuth Axis: 400° (± 200°)
Elevation Axis: 190° (± 95°)
� 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 and TH003 are available in
lieu of rotary joint and/or slip ring options.
� 4 AL-4368-1 and larger models are delivered standard
with synchro.
