Our vacuum compatible piezo stack actuators are equipped with a highly reliable, multi-layer, low-voltage, piezoelectric transducer stack. They are internally pre-loaded by a mechanical spring and feature high resonant frequencies, making them ideal for high load, dynamic vacuum applications.

With positioning resolution as low as 0.05 nm, the NPA Piezo Stack Actuators make ultra-fine adjustments with resolution only limited by the noise of the control electronics.
NPA Piezo Stack Actuators can generate large forces up to 1000 N which make them particularly useful for machine tools, active vibration isolation, or adaptive mechanics.
Closed-loop versions feature high resolution strain-gauge position sensors for highly accurate and repeatable motion which also compensates for actuator creep. The assembly is done as a full Wheatstone bridge and is temperature insensitive. The closed-loop devices can be used in either open or closed-loop control.
