Stack type actuators series PA

Share this on social media:

Piezosystem Jena has launched stack type actuators series PA. These actuators, based on multilayer ceramics, are internally preloaded with a mechanical spring. Due to the high resonant frequency they can be used in applications such as scanning microscopy, laser fine tuning, micro manipulation or mirror positioning.

The actuators can sustain high compressive forces or loads with tensile forces, and are characterised by their high stiffness of up to 85N/μm and large travel ranges up to 220μm.

The series PA are available with a M3 thread top plate or ball tips. Vacuum and low temperature versions are also readily available. Furthermore, they can be combined with a sensor to achieve nanometre accuracy. The uniform diameter is 14mm.
