| | | ■ Frictionless Precision Flexure ■ Very Compact ■ Low Cost ■ Travel to 100 um ■ XY and XYZ Combinations P-280 Piezo flexure stages are compact and cost effective positioners and industrial scanners. They are available in three different sizes, with displacements of 30, 50 and 100 um. P-280 stages can be mounted in either a vertical or horizontal position, to easily adapt to specific mounting requirements. Working Principle P-280 positioners are equipped with high-voltage piezoelectric contraction strip industrial actuators integrated into a flexure guiding system. The force exerted by the piezo moves a flexure parallelogram. The wire-EDM-cut | | Guiding System | | |
