MPO Piezo Stacks

to product overview

MPO show the following outstanding properties:

Large strain of ca. 1.5 ‰ at 0 to 150 V
>2 ‰ strain in the extended voltage-range of -45 to 180 V
Consequently laminated structure and monolithic sintering guarantee best possible dimensional tolerances and straightness of motion
Avoiding of micro-cracks and the pillow-effect at simultaneous insulation-safety is achieved by µm-precise definition of the electrodes (drawn back) in combination with an elastic isolation
