Model 935 Rotary Servo Actuator
The Model 935 is one of the highest performance rotary servo actuators available on the market. We offer this actuator with a digital and analog communications interface. Also, we can customize the actuator to provide up to ±90 degree angular excursion in a slightly longer package. These options allow our customers flexibility based upon the architecture in the system to have a drop-in servo actuator.
