PHYSIK Instrument, represented by Warsash Scientific , has released the PICA-Stack series of piezoceramic linear actuators.
The actuators come in a variety of load ranges from 100N to 100,000N and can generate forces of up to 80,000 N. Typical applications include optics, smart structures, precision machining, valve control, nanopositioning and nanotechnology.
They are designed for high-duty-cycle applications. Endurance tests on the actuators show consistent performance after billions of cycles.
The actuators are available in a variety of sizes and shapes, circular, square and triangular. Through-hole designs are standard. Options include special high/low temperature versions, nonmagnetic versions and vacuum compatible versions.
