Multilayer piezoactuators are excellent when you need high pushing force and fast response. But their movement ranges are small for many applications. In such cases, you can use our amplified piezo actuators.

In addition to backlash-free movement, APA-220U provides enough preload force on piezo stacks for dynamic applications.


  • Free stroke up to 220 μm

  • High stiffness up to 0.34 N/μm

  • Preloaded for dynamic operations

  • Simple screw mounting interface

  • Flexure guides for zero play

  • Strain gauge feedback for closed-loop control
