Drawings / images PICMA® Stack actuators, dimensions in mm. L, A, B, see data table. Specific tips (tips and bases) can be mounted for mechanical coupling of the actuators. Possible designs are flat or spherical tips made of metal, ceramics, glass or sapphire. Application-specific tips can be manufactured on request.

For high dynamics applications, the multilayer actuators are equipped with electrodes for especially high currents of up to 20°A. Together with a high-power piezo amplifier such as the E-618, high operating frequencies in the kHz range can be attained. The rise times for the nominal displacement are a few tens of microseconds.
