Features

Sub-Nanometer Positioning Resolution

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.

Ultra-High Load Capacity

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.

Optional Strain-Gauge for Closed-Loop Operation

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.

Vacuum Compatible Versions

The NPA Piezo Stack Actuators are available in vacuum compatible versions which can be used in vacuum (10-6 Torr) environments.
