Compact, Low Cost, Accurate: Mini Positioning Stages, by PI

Precision positioning systems specialist Physik Instrumente (PI) LP recently introduced a new miniaturized, piezo-driven linear positioner - the Q-521. Joining PI’s existing Q-Motion linear and rotary positioning solutions product line, the ultra-compact Q-521 is only 21mm wide, and comes with travel ranges of 12mm, 22mm, and 32mm.

Q-521 Ultra-Compact, Economical in Open and Closed-Loop

Several options are available for the Q-521 stage series, from economical open-loop designs, to low-cost closed-loop versions and high-end feedback sensors providing 1nm resolution. Vacuum compatible stages, and UHV and a non-magnetic option are also offered.

Features & Advantages

• Ultra Compact: 21x30x10mm (Closed-Loop Version)
• Integrated Linear Encoder
• 1nm and 4nm Resolution Available
• XY Configurations w/o Adapter Plate
• 12, 22, and 32mm Travel Range
• 10mm/sec Max. Velocity

Stick-Slip Gearless Cost-Efficient Drive System

Stick-slip drive motors, lacking gears, are powered by the natural difference in the static and dynamic friction coefficients found between two surfaces. This direct linear motion drive principle reduces the number of components that can wear, making the stages more compact, reliable and cost efficient. PI stages and drives can be customized for larger production quantities.

Self-Clamping at Rest, High Stability

The self-clamping motor design provides long-term power-off position-hold capabilities without the need for a brake -- another space and energy saving advantage of the Q-Motion positioner series.

Applications of the Q-Motion Miniature Linear Stages

Precision positioning and alignment of compact opto-mechanical components both in research and OEM instrumentation. Fields of application include photonics, bio-technology, nanotechnology, precision-optics, life-sciences and medical design.
