A12 3-Position Rotary Actuator

a12 3-position rotary actuator
A12 Dual RAck 3-Position Rotary Actuator


With internal stops for an intermediate position, our A12 three-position actuator has overall dimensions that are similar to those of its two-position counterpart, the A12 rotary actuator. Output torque is that of a single rack unit but it can rotate to any of its 3 positions in any sequence by simply activating the proper directional control valve.
