Specification

nanoFaktur HPa (HPO and HPS), encapsulated and preloaded piezo-stack actuators, are easy to handle and immediately employable. HPa exclude the risks, which otherwise come with bare and open stacks. The versions HPS have integrated temperature compensated position-metrology: strain-gage-sensors (SGS) in full-bridge configuration. There are M3/M4 threads in bottom- and top-pieces for facilitating the mounting. The actuators show higher strokes at the same dimensions than competitors´products. Nominal voltages from 60 to 200 V are available. The stacks have no electrical connections to the casings or the shieldings for maximum safety of the users and the realm. The 60 V versions (-30.. 30 V) are ideal for safety-relevant applications, like in medical products. Stacks made of optional loss-reduced (hard) ceramics are perfectly suited for high-dynamic applications. Hermitical sealing, waterproof, encapsulations are available for industry applications.
