Stack type actuators series PA/T0 pages

Series PA/T
stack type actuator with outside threading
Positionierer
Concept:
The series PA/T based on stack type actuators in
multilayer design. They are mechanically preloaded to make them ideal for dynamic applications.
The series PA/T have an M14 outside threading
that can be used to mount the actuator; it also
helps to lock in the position precisely. The ball tip
end plate allows movement of components without shear stress on the ceramic inside. Therefore
these series of actuators are well suited for high
precision mirror adjustment or for integration into
optical systems to realize beam steering in real
time.

Specials:
The series PA/T can handle loads up to 850 N. The
housing of the actuator, in combination with built-in
springs, allows a motion without mechanical play.
Maximum motions up to
105 µm are available depending on model.
To overcome the effect of drift and hysteresis, the
actuator can be equipped with a high resolution
strain gage feedback sensor. The typical accuracy is
0.5% of the used motion.

Mounting / Installation:
A Special feature is the outside threading of M14
to mount the actuator. It also helps to adjust the
position precisely.
These actuators are mechanically preloaded to
make them ideal for dynamic applications. The
ball tip end plate allows movement of components
without shear stress on the ceramic inside.
The given preload does not exceed while the
actuator is used dynamical.
