Our Performance Series AZ/EL 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.
