Description

P/S piezo actuators have a hermetically sealed housing that allows for use in aggressive and humid environments. The construction of the housing tightly encloses the stack, also reducing mechanical play.

The M3 thread in the bottom plate allows for easy adaptation in existing systems and guarantees exact positioning.

Depending on the model, these piezo actuators offer motion from 18 µm up to 70 µm.
