End-pieces for actuator plate stacks for easy integration

Noliac introduces end-pieces with a spherical cap for piezo actuator plate stacks. The end-piece facilitates integration in the application for the customer. The added thickness provided by the end-piece is also an effective way of spreading the load on the actuator.

Providing de-coupling and increasing robustness
The end-piece with a spherical cap prevents undesired coupling between subsystems. For example, if the actuator is driving a flexure-guided stage, the end-pieces prevent the actuator from inducing unwanted stress in the flexures, and vice-versa. Adding end-pieces to an actuator plate stack also increases the robustness of the actuator, since the stainless steel of the end-piece can tolerate higher stress concentrations compared to the ceramic. This end-piece is also UHV compatible.

Expanding our options to match your requirements
Our options are designed to make the integration of the piezo actuators in the specific applications easier for our customers. We constantly review our options and look for ways to expand the range in order to offer the most extensive selection of options for our customers.

Product range
At present, we offer the end-piece with these 3 square sections: 5x5 mm, 7x7 mm and 10x10 mm. These products are compatible with:
