PI has expanded its PICMA piezo stack actuator series with the launch of new encapsulated PICMA actuators. Piezo actuators use solid-state motion to deliver high speed, high force, and virtually unlimited resolution, suitable for precision positioning and alignment applications. The new encapsulated actuators offer travel ranges from 56 to 132 µm and blocking force of 1200 N. The splash resistant full encapsulation protects the piezo ceramics from oil, water, chemicals and particles in industrial applications. The actuators are also vacuum compatible.
The new encapsulated actuators use PI’s polymer-free multilayer piezo stacks. Their patented ceramic encapsulation provides extra protection from humidity. This robust design ensures exceptional durability, proven by NASA/JPL’s 100-billion-cycle test for the Mars rover Curiosity. PICMA actuators offer reliable performance in harsh environments, with humidity resistance and an operating range from -40° C to 150° C and up to 200° C for modified versions.
Other features include a high degree of stiffness, microsecond response time, and UHV-compatibility to 10-9 hPa.
Industrial applications for the new piezo stack actuators include micro-manufacturing, nano-dispensing, optics & photonics, semiconductor test equipment, astronomy, med-tech, biotechnology, and nanopositioning.
