Intelligent Linear and Rotary Motion in One


The WITTENSTEIN ternary® actuator is the all-in-one linear actuator system that merges mechanics with intelligence - integrating controller, motor, amplifier and drive into one compact mechatronic device. Designed to meet the requirements for linear or rotary compact motion, the ternary® expands upon the alpha gearbox competencies by combining WITTENSTEIN's robust electronic expertise which has seen success for over a decade in military and aerospace markets.

 For rotary motion, the basic ternary® device can be used alone or paired with an alpha gearbox. For linear requirements, a ballscrew or slider is added to the device. With complete integration and ease of programming, the ternary® represents the best in efficient engineering. Setting parameters for functions is easy with the included programming software. Depending on the type of operation, the designer can also write a program that contains specific positions and motion profiles. With low voltage requirements, variety of control interfaces and no maintenance, the ternary® all-in-one system is ideal in new applications as well as for retrofits and upgrades for pneumatics.
