Piezo actuator with high resonant frequency PU 65 HR0 pages
PU 65 HR
Compact 1-axis translation stages
Concept:
PU translators consist of a single metallic part
which includes the flexure guiding system. This
design means that PU translation stages show
excellent mechanical stability and, because they
are pre-loaded, can work dynamically. The FEA
modeled flexures guarantee zero friction and high
robustness. These actuators can support high
loads and generate single axis motion of 40 to
100 microns. They are easily adaptable because
they can be mounted both horizontally and
vertically. The rugged design makes the PU
series well suited for all kinds of industrial
applications where reliable sub-nanometer
accuracy is needed.
A special translator, the PU 65 HR, has been
optimized for a high resonant frequency which is
ideal for scanning applications.
Specials:
The systems may be specially prepared for
vacuum and/or cryogenic applications. Other
materials, such as nonmagnetic stainless steel,
anodized aluminum, or titanium, are also
available.
Interfaces:
The elements of the PU series consist of one
monolithic element. The direction of motion is
shown in the drawings. Please note that there
must be a space between the translator and the
plate to which it is fixed, otherwise movement may
be blocked and not parallel. Precision pin holes
provide the means for very accurate mounting of
the PU translators.
The PU series can be loaded with tensile forces
defined by the specified pull force values for each
element.
