Available in open-loop and closed-loop versions measuring 21 mm wide, Series Q-521 offers travel ranges of 12, 22, and 32 mm. Piezo-driven linear positioners are based on stick-slip gearless motor principle with self-clamping motor design that provides long-term power-off position-hold capabilities without need for brake. Equipped with integrated linear encoder, stages provide precision positioning and alignment of compact opto-mechanical components in research and OEM instrumentation.
