The compact N-380/N-381 piezo walk linear actuators have a number of advantages over classical lead-screw actuators. The novel drive principle allows long travel ranges and rapid accelerations, for high-dynamics / high-throughput applications.

An “analog mode” can be used for fast oscillations with amplitudes of several microns and frequencies to several 100 Hz. Open-loop and closed-loop models are available: the N-381 model is equipped with a high-resolution position sensor, allowing sub-micron repeatability. The N-380 open-loop version is intended for high precision applications where the absolute position is not important or is controlled by an external loop (video, laser, etc.).
