Johnson Electric’s Ultimag® rotary actuator technology offers a bidirectional, center return function not found in traditional rotary solenoids. The Ultimag platform is substantially faster than other solenoids, and can be operated in an on/off mode or proportionally, in both open and closed loop systems. Ultimag actuators offer a 45° stroke; however, the design is capable of a maximum stroke of 160°. For shorter strokes, electronic or mechanical stops can be used. This technology is ideal for applications requiring high speed and high torque motion control often found in industrial, business technology and medical applications.
