KEMET Multilayer piezoelectric actuator AHB

Multilayer piezoelectric actuators are ceramic elements used to convert electrical energy into mechanical energy such as displacement or force by utilizing the piezoelectric longitudinal effect.

KEMET’s multilayer piezoelectric actuators are produced based on our unique element structure design and piezoelectric ceramic materials with high electrostrictive factors. Compared to conventional piezoelectric actuators, they are smaller in size but can generate higher displacements and forces at low voltages.

The AHB metal sealed 85°C high perfomance series actuators are less impacted by ambient humidity due to insulation from the atmosphere. As a result, long operational life and high performance have been attained which are ideal for use in various high reliability applications such as semiconductor device production equipment and optical communication equipment.
