Piezo bimorph disc actuators belong to the group of piezoelectric actuators. These high-resolution PZT actuators can be used in dynamic and static operation providing nanometer precision motion and fast response.
Compared to piezo stacks, they provide for a relatively large travel range in an extremely small package. P-286 can be attached to a flat surface with the outer ring. The translator expands via the central tapped connector. P-288 and P-289 are double disk constructions where the expansion occurs between the two facing tapped connectors.
For the highest displacement, amplified piezo actuators with flexure guides are recommended.
Application Examples:
Static and dynamic positioning, pneumatic valves, patch clamping, etc.
