Rotary Positioners

Performance Series - AZ/EL Positioners: Medium Duty

The MVG-Orbit/FR performance series has recently been expanded to include medium-duty, dual-axes positioners: the new AL-438X series. Thanks to their low profile design and advanced drive mechanism, these symmetrical AZ/EL positioners ensure 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. This particular series provides a counter weight option which improves overall system stability and accuracy while allowing for higher DUT loads. A large variety of options is available for this ORBIT/FR standard product family.
