9 Cycles Flexibility: PI Ceramic’sStrength Special High / Low Temperature Versions Proven and Flexible Design Sub-Nanometer-Resolution / Sub-Millisecond-Settling-Time All manufacturing processes atPI Ceramic are set up for flexi- bility. Should our standard actuators not fit your applica- tion, let us provide you with acustom design. Our engineers will work with you to find the optimum solution at a very attractive price, even for small quantities. Some of our cus- tom capabilities are listed be- low: Vacuum Compatible Versions Short Leadtime, Standard &Custom Designs Vacuum-Compatible Versions Because all piezoelectric mate-rials used in PICA™ actuators are manufactured at PI Ceramic, leadtimes are short and quality is outstanding. All standard and custom PICA™-Stack actuators are deliveredwith performance test sheets.
Custom PICA™-Stack actuator with 350 µm displacement. PICA™-Stack dimensions, see technicaldata table for further information. PICA™-Stack piezo ceramicactuators are offered in a largevariety of standard shapes and sizes with additional custom designs to suit any application. Amplifiers, Drivers &Controllers Ultra-High Reliability, HighDisplacement, Low PowerRequirements PI offers a wide range of con-trol electronics for piezo actua- tors, from low-power drivers to multi-channel, closed-loop, digital controllers. Of course, PIalso designs custom amplifiersand controllers. PICA™-Stack actuators arespecifically designed for high- duty-cycle applications. Withour extensive applicationsknowledge, gained over sever-al decades, we know how to build 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™actuators 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 excellentdynamic behavior with reduced driving power require- ments.
