Ring stacks

Ring stacks

Noliac multilayer piezo ring actuator stacks can be stacked to fit the needed height or stroke. Maximum height and stroke are 200 mm and 326.7 µm for our standard products. The ring stacks are used in a wide selection of applications due to the easy integration of a ring shape.
