ACTuatorBare - Bare stacks - Perfect for integration into customized mechanism.

Co-fired multilayer piezo stack - thin coating type

A full range of sizes and options are available. Nominal operation voltage of the co-fired multilayer piezo stack is 150 V. The stacks are characterized by high power density, providing strong, precise and fast actuation for your applications.

Semi-bipolar operation from -30 V to 150 V.

Options: cryogenic, vacuum, thin coating, thick coating, endplates: steel, ceramics, spherical, strain gauges.

Piezo stack actuators, monolithic co-fired piezoceramics stacks — Co-fired multilayer piezo stack - thick coating type

Piezo stacks with rectangular as well as cylindrical shape are available. Ring-shaped stacks are choices for optical applications or space critical mechanical designs. Hole-through stacks and special designs are available on request. Actuator with thick coating on request.

Metal sealed type  are hermetically encasing the piezo stack. This is a perfect solution for difficult environments such as humid workplaces with rel. humidity higher than 60%, oil spray or dew conditions. The piezo stack is protected in a stainless steel package. A broad range of actuators are available for all sizes and with different mounting brackets (female thread type or flange type).

Stock items can be ordered directly from this site. Custom solutions are available from 1 mm x 1 mm x 1 mm to very large stack actuators e.g. 25 mm x 25 mm x 200 mm.
