P-286, P-288, P-289 Bimorph Piezo Disk Translators With Long Travel Range

  • Displacement to 200 µm
  • Sub-nm Resolution
  • Low Cost
  • Flat Design
  • For Small Forces
  • Displacement to 200 µm

 

Disk Translators belong to the group of bimorph piezoelectric actuators translators are high resolution actuators for static and dynamic applications providing fast response and sub-nanometer resolution.

Compared to stack translators, they provide for a relatively large travel range (up to 200 µm) 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.



Application examples:

Static and dynamic positioning, pneumatic valves, patch clamping, etc.
