NewScale M3 RS U with mirror TEXT horiz

M3-RS-U Rotary Smart Stage: Rotary micro stage with built-in closed-loop controller is the easy, all-in-on solution for embedded micro motion.

New Scale rotary micro stages and positioning modules feature our patented piezoelectric motors along with integrated position sensors, bearings, drive electronics and embedded firmware.

These “smart stages” have all electronics integrated into the compact rotary micro stage – no external controller required. Along with smallest system size, this makes for fastest, easiest integration into your handheld and portable systems.

High precision, smallest size and unmatched ease of use
