Standard piezo stack program

On request, longer stacks can be manufactured in the factory as assemblies based on the standard types. Customer-specific piezos with lengths in steps of 9mm: stack length 9, 18, 27, 36, 45, 54, ... 180 mm and longer.

Customized Piezos. Piezo stacks with rectangular  as well as cylindrical shape are available. Ring-shaped stacks are choices for optical applications. Hole-through stacks and special designs are available on request. Actuator with thick coating (green colored) are also available on request.

Metal sealed type
 are hermetically encasing the piezo stack which is sensitive to excessive humidity.

Metal casing is a perfect solution for difficult environments such as humid workplaces when the relative humidity is higher than 60%, oil spray or dew condition. 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).
