PI has introduced 4 new series of high-force, highly dynamic piezoelectric stacked actuators with high vacuum options, complete with a new line of linear amplifiers. While most low and medium force actuator applications are covered by the company's patented PICMA multilayer technology, the PICA stacked actuator technology enables applications where extremely high forces and dynamics are required or high levels of customization are needed
The four newly developed piezo actuator series (P-212, P-216, P-225 and P-235) are equipped with the advanced PIC 255 PICA power piezoceramic stacks. They come with load capacities from 2,000N to 30,000N and travel ranges from 15 micro metres to 180 micro metres. 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 ideal for dynamic applications and push-pull applications. 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 2000 watts of power are available to drive the new preloaded piezo actuators. All models are delivered preset to provide 0 to 1000V output voltage and most can also be run in bipolar mode.
