Multilayer Piezoelectric Actuators
AHB Series Metal Sealed 85°C, High Performance
Overview
Applications
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.
TypicalꢀapplicationsꢀincludeꢀfineꢀadjustmentꢀofꢀvariousꢀX-Yꢀ
tableꢀsteppers,ꢀmirror/prismꢀpositioning,ꢀlinearꢀmotors,ꢀfluidꢀ
flowꢀcontrolꢀvalveꢀdrive,ꢀvibrationꢀsourceꢀandꢀmanipulators.
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.
