The product You were Looking for was moved Click Here for new Address P-286 P-288 P-289 HVPZT Disk Translators Displacement to 200 µm Sub-nm Resolution Low Cost Flat Design Disk translators belong to the group of bimorph piezo actuators (see "Tutorial: Piezoelectrics in Positioning" section for description of design principle). P-286 to P-289 translators are high-resolution actuators for static and dynamic applications providing fast response and sub-nanometer resolution. Compared to stack translators, disk translators provide a relatively large travel range (up to 200 µm) in an extremely small package. The P-286 can be attached to a flat surface with the outer ring. The translator expands via the central tapped connector. P-288 and P-289 are double-disk constructions where the expansion occurs between the two facing tapped connectors. Accessories Extension cables & connectors: see link in the "PZT Control Electronics" section. Static and dynamic positioning Pneumatic valves Patch clamping For more examples see link Disk translators: P-289 (top, left), P-288 (center), P-286 (right, top and bottom view) with microprocessor for size comparison P-288 dimensions (in mm) P-289 dimensions (in mm) P-286.xx dimensions (in mm)
