Rotary Positioners

Performance Series - EL/AZ Positioners: Heavy Duty

The Performance Series 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.

These positioners provide accurate, balanced rotation, and controllable velocity. Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation, yielding the best size and weight/performance ratio. Typically, the unit includes the body, precise slew bearings, DC motor, gear reducer, encoder/synchro, and limit switch assemblies. The AUT mounting surface is designed with a threaded mounting hole pattern for ease of use. A Safe/Operate switch is included to ensure safety.
