Piezoelectric (PZT)
Actuators and Ceramics

Piezoelectric Actuators are solid state (ceramic) actuators that convert electrical energy directly into motion (mechanical energy) of extremely high resolution.

Quality and Selection

PI offers the largest selection of research and industrial-reliability Piezo Actuators and Translators (linear actuators) worldwide. In addition to the hundreds of models presented in this catalog, we manufacture custom designs tailored to customers’ requirements. PI is highly vertically integrated, controlling each manufacturing step from PZT raw materials to finished systems.
