™ -Thru actuators are hol-low piezo stack actuators,offered in a large variety of
standard shapes and sizes with
additional custom designs to
meet all customer require-
ments. They combine the
advantage of a clear aperturewith the strength and forcegeneration of stack actuators.
These tubular devices are high-
resolution
linear actuators for
static 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 piezo actuators arespecifically designed for high-
duty-cycle applications. With
our extensive applications
knowledge, gained over sever-al decades, we know how tobuild performance that does
not come at the price of relia-
bility. All materials used are
specifically matched for
robustness and lifetime.Endurance tests on PICA
™ PICA ™ -Thru piezo actuator dimen-sions, see technical data table for
further information.
PICA actuators are delivered with
performance test sheets. Flexibility: PI Ceramic’sStrength
™ actu-ators prove consistent per-
formance, even after billions
(1,000,000,000) of cycles. The
combination of high displace-ment and low electrical capaci-tance provides for excellent
dynamic behavior with re-
duced driving-power require-
ments. All manufacturing processes atPI Ceramic are set up for flexi-
bility. Should our standardactuators not fit your applica-
tion, let us provide you with a
custom design. Our engineers
will work with you to find the
optimum solution at a veryattractive price, even for smallquantities. Some of our cus-
tom capabilities are listed be-
