產品說明
Series RA ring actuators consist of a large number of contacted ceramic discs. Compared with a tube actuator, the ring actuator reaches a higher stiffness and the expansion is twice as high.
Series RA piezo actuators are encased, and also include a mechanical pre-load so they can be used in dynamic applications.
Series RA actuators are available for open-loop systems, and closed-loop (strain gauge) systems.
