Model 935 Rotary Servo Actuator

Model 935 Rotary 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.

Operating Voltage 21 to 32 VDC
Operating Temperature Range -40° to +71° C
Operating Altitude Range -1,500 to +65,000 ft
Weight 3.7 - 3.9 lbm max
