series N Stack type actuators without casing Concept: PZT multilayer stack type actuators are made for industrial applications. They are specially shielded by a flexible insulation material which guarantees the highest possible dynamic performance under the toughest requirements. Based on their design, they are well suited for easy integration into specific customer systems. The flexible polymer coating material gives the PZT actuators proven protection against various and harsh environments. The advantage of a flexible insulation versus brittle ceramic insulation is a longer lifetime. These PZT multilayer stack type actuators have been successfully working for more than 15 years in a vast number of applications in the fields of nano-metrology, semiconductor, material sciences and scanning applications. Specials: PZT multilayer stack can be used in cryogenic applications down to a few Kelvin. They can also be used in vacuum atmosphere conditions as well. The Curie temperature for baking is 150°C. Mounting: It is rather important, not to subject the actuator tip to non-axial forces during the manufacturing process and use. To assist the mounting of the ceramic, ball tip end plates and flat tungsten carbide endplates are available in different sizes. The standard cable length is 100mm. As an option, flat tungsten carbide or ball tip end plates are available. The PZT multilayer stacks are not pre-loaded. Product highlights: • PZT multilayer stack without housing • without pre-load • motion up to 123pm • flexible mounting • unlimited resolution • flexible epoxy insulation to guarantee long life Applications: • positioning application demanding high accuracy under high load environment conditions, long lifetime, permanent movement in industrial applications
