Linear actuator series

The series of piezoceramic linear actuators called the PICA Stack actuators from Physik Instrument (PI), come in a variety of load ranges from 100 to 100,000 N can generate forces up to 80,000 N. Typical applications include optics, smart structures, precision machining, valve control, nanopositioning and nanotechnology, and other applications where nanometre precise motion, fast response and/or high forces are required.

The actuators are specifically designed for high-duty-cycle applications. All materials used are matched for robustness. Endurance tests on the actuators claim to prove consistent performance, even after billions of cycles.

The actuators are available in a variety of sizes and shapes, from circular to square, and triangular, and even through-hole designs are standard. Options include special high/low temperature versions, non-magnetic versions and vacuum-compatible versions.
