> Rotary Positioners

Our Legacy Series AZ/EL 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 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.
