PICATM-Thru Piezo Stack Actuators with Aperture P-010.xxH P-016.xxH P-025.xxH 

  • Clear Aperture for Transmitted-Light Applications
  • Large Cross-Sections Available (to 56 mm Diameter)
  • Variety of Shapes
  • Extreme Reliability >109 Cycles
  • Proven and Flexible Design
  • Sub-Nanometer Resolution / Sub-Millisecond Settling-Time
  • Vacuum Compatible Versions

PICATM-Thru actuators are hollow piezo stack actuators, offered in a large variety of standard shapes and sizes with additional custom designs to meet all customer requirements. They replace the P-305 / P-306 series and combine the advantage of a clear aperture with the strength and force generation of stack actuators.

Ultra-High Reliability, High Displacement, Low Power Requirements
PICATM piezo 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 PICATM 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 set up 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
  • Custom Displacement
  • Custom Load / Force Ranges
  • Custom Endplates (Alumina, Glass, Sapphire, ...)
  • Extra-Tight Length Tolerances
  • Custom-Molded Versions
  • Integrated Piezoelectric Sensor Discs
  • Low Temperature Versions
  • Vacuum Versions

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

Amplifiers, Drivers & Controllers
PI offers a wide range of control electronics for piezo actuators (see page 28 and www.pi.ws) from low-power drivers to multi-channel, closed-loop, digital controllers.

Of course, PI also designs custom amplifiers and controllers.
