™ -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 forrobustness and lifetime.Endurance tests on PICA
™ actu-ators prove consistent per- formance, even after billions (1,000,000,000) of cycles. Thecombination of high displace-ment and low electrical capaci- tance provides for excellent dynamic behavior with reduced driving power require- ments. All manufacturing processes atPI Ceramic are set up for flexi- bility. Should our standardactuators 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 smallquantities. Some of our cus-tom capabilities are listed be- low: Amplifiers, Drivers &Controllers
Application Examples 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.
