Stacked actuators handle extreme forces
PI's PICA stacked actuator technology suits applications where extremely high forces and dynamics are required or high levels of customisation are needed.
PI has introduced four new series of high-force, high-dynamics piezoelectric stacked actuators and a new line of linear amplifiers While most low and medium-force actuator applications are covered by the company's PICMA multilayer technology, the PICA stacked actuator technology suits applications where extremely high forces and dynamics are required or high levels of customisation are needed

Long range for PZT steering mirror
Polytec PI, NanoPositioning Group, has released what it claims to be the world's longest-range high-speed PZT-driven two-axis mirror scanner.
Stages go a long way accurately
Polytec describes Hera as the world's longest-travel precision-guided PZT nanopositioning stages for advanced applications such as mask alignment, inspection and metrology.
The P-212, P-216, P-225 and P-235 piezo actuators are equipped with the PIC 255 PICA Power piezoceramic stacks.
They come with load capacities from 2000 to 30000N and travel ranges from 15 to 180um.
Over 100 standard models are offered.
All actuators provide sub-nanometer resolution and are available with position feedback for better positioning accuracy.
The integrated preload makes these actuators suitable for push-pull applications and dynamic applications such as precision machining and active vibration damping.
The low-capacitance, piezo ceramics require less electric power than similar actuators - a special advantage for high dynamics applications.
Five RoHS-compliant high-voltage amplifiers ranging from 1 to 2000W of power are available to drive the preloaded piezo actuators.
The E-462, E-464, E-508, E-421 / E-470 / E-471 / E-472, E-481 models are delivered preset to provide 0 to 1000V output voltage and most can also be run in bipolar mode.
PICA Power actuators are optimised for high-duty-cycle dynamic applications and high-temperature working conditions.
All materials used are specifically matched for robustness and lifetime.
Endurance tests on PICA actuators prove consistent performance, even after billions of cycles. Request a free brochure from PI (Physik Instrumente) ...
