Description
The nanoFaktur HPO and HPS ranges of encapsulated and preloaded piezo-stack actuators have been designed to be long lasting and easy to use. There are M3 or M4 mounting threads at each end of these units. The actuators have longer strokes than any other manufacturer’s, and nominal voltages from 60 to 200 V are available. The stacks have no electrical connections to the casings or the shielding in order to maximise user safety, and the 60 V versions (-30 tp +30 V) are ideal for medical products. Stacks made of optional loss-reduced (hard) ceramics are perfectly suited to high-dynamic range applications. Hermetically sealed waterproof encapsulations are available.
