25% more stroke of 2x2x2 mm actuator

Noliac’s 2x2x2 mm multilayer piezo actuator has 25% higher free stroke than competitive products. Displacement is 2.8 μm and it is available for stacking granting you up to 21 μm free stroke. This is unique in the world of nanomotion.

Ceramic Multilayer Actuator

Noliac's single ceramic multilayer actuators, plates and rings, can be stacked. Thereby, the height can be made according to your needs. Noliac's stacking technology also offers a unique manufacturing flexibility as any actuator height can be made from a defined number of single actuators.

2x2 mm stack

Small with high displacement

The Ceramic Multilayer Actuator Plate 12 (CMAP12) has been produced by Noliac previously, but has now become a standard product due to increased demand.

- The CMAP12 has very high stroke within very small dimensions, Global Sales Manager Cedric Goueffon states. – The 2x2x2 mm grants you more than 25% higher stroke than  competitive products, and our ability to stack the component 10 times is unique.

- If you need precision in miniature form, this is your solution! It can fit anywhere, Cedric adds up.
