Amplified Actuators

This range of Piezoelectric actuators have been developed to provide large displacements for use in applications where space is limited. These Piezo actuators represent an economical approach to obtaining large displacements where very high force is not a requirement but nanometer resolution is still desired.

The Piezoelectric actuators are enclosed in a stainless steel housing and contain multilayer Piezo actuators fabricated using Kinetic Ceramics' proprietary PZWT-100 ceramic which has high unit strain with low hysteresis. The proprietary ceramic fabrication techniques result in low porosity and high density and attain superior reliability. The patented method of bonding and encapsulation gives excellent mechanical strength, stiffness and  suppresses breakdown in high electric fields. When activated, these Piezoelectric actuators generate no electromagnetic field and require no holding current.

If none of the sizes below meet your application requirements our actuators can be fabricated in custom configurations to exactly match special requirements with fast turnaround times.
