Notes
PICA^TM-Stack actuators are delivered with metal endcaps for improved robustness and reliability. Adherence to the mounting and handling guidelines on page 50 will help you obtain maximum performance and lifetime from your piezo actuators. Please contact a PI Ceramic applications engineer for additional technical support.


PICA^TM-Stack piezo ceramic actuators are offered in a large variety of standard shapes and sizes with additional custom designs to suit any application.

Ultra-High Reliability, High Displacement, Low Power Requirements
PICA^TM-Stack actuators are specifically designed for high-duty-cycle applications. With our extensive applications knowledge, gained over several decades, we know how to build performance that does not come at the price of reliability. All materials used are specifically matched for robustness and lifetime. Endurance tests on PICA^TM actuators prove consistent performance, even after billions (1,000,000,000) of cycles. The combination of high displacement and low electrical capacitance provides for excellent dynamic behavior with reduced driving power requirements.

Flexibility: PI Ceramic's Strength
All manufacturing processes at PI Ceramic are setup for maximum flexibility. Should our standard actuators not fit your application, let us provide you with a custom design. Our engineers will work with you to find the optimum solution for your application at a very attractive price, even for small quantities. Some of our custom capabilities are listed below:

• Custom Materials
• Custom Voltage Ranges
• Custom Geometries (Circular, Rectangular, Triangular, Layer Thickness ...)
• Custom Displacement
• Custom Load / Force Ranges
• Custom Flat or Spherical Endplates (Alumina, Glass, Sapphire, ...)
• Extra-Tight Length Tolerances
• Custom-Molded Versions
• Integrated Piezoelectric Sensor Discs
• Special High / Low Temperature Versions
• Vacuum Compatible Versions

Short Leadtime, Standard & Custom Designs
Because all piezoelectric materials used in PICA^TM actuators are manufactured at PI Ceramic, leadtimes are short and quality is outstanding. All standard and custom PICA^TM-Stack actuators are delivered with performance test sheets.

Amplifiers, Drivers & Controllers
PI offers a wide range of control electronics for piezo actuators (see section 6 and www.pi.ws) from low-power drivers to multi-channel, closed-loop, digital controllers. Of course, PI also designs custom amplifiers and controllers.
