> Rotary Positioners

ORBIT/FR Legacy Series azimuth positioners provide
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 bearing, DC motor, gear reducer,
synchro assembly, and limit switch assembly. 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.
