PICA™-Thru Piezo Stack Actuators with Aperture (HVPZT)
Flexibility: PI Ceramic’sStrength All manufacturing processes atPI Ceramic are set up for flexi-
bility. Should our standardactuators not fit your applica-
tion, let us provide you with acustom design. Our engineerswill work with you to find the
optimum solution at a very
attractive price, even for small
quantities. Some of our cus-
tom capabilities are listed be-
low: Ultra-High Reliability, HighDisplacement, Low Power
Requirements Custom Materials Custom Voltage Ranges PICA™
piezo actuators arespecifically designed for high-duty-cycle applications. With
our extensive applications
knowledge, gained over sever-
al decades, we know how to
build performance that doesnot come at the price of relia-bility. All materials used are
specifically matched for
robustness and lifetime.
Endurance tests on PICA™
actuators prove consistent per-
formance, even after billions(1,000,000,000) of cycles. Thecombination of high displace-
ment and low electrical capaci-
tance provides for excellent
dynamic behavior with re-
duced driving-power require-

Piezoelectric sensor Discs Proven and Flexible Design Low-Temperature Versions Sub-Nanometer Resolution / Sub-Millisecond Settling-Time Vacuum Versions Vacuum Compatible and Nonmagnetic Versions Short Leadtime for Standard& Custom Designs PICA™-Thru actuators are hol-low piezo stack actuators,
offered in a large variety of
standard shapes and sizes withadditional custom designs tomeet all customer require-
ments. They combine the
advantage of a clear aperture
with the strength and force
generation of stack actuators.
These tubular devices are high-resolution
linear actuators forstatic and dynamic applica-
tions. Because all piezoelectric mate-rials used in PICA™ actuatorsare manufactured at PI
Ceramic, leadtimes are short
and quality is outstanding. All
standard and custom PICA™
actuators are delivered withperformance test sheets.
