The product You were Looking for was moved Click Here for new Address P-249 Miniature Open-Loop HVPZT Translators Displacement to 10 µm Sub-msec Response Sub-nm Resolution Options: UHV, High- & Low-Temperature P-249 miniature PZT translators are high-resolution linear actuators for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. Due to their high resonant frequency, these translators are ideal for dynamic operation of very light parts. For dynamic operation with larger loads, an external preload is recommended. PI offers a variety of preloaded translators for applications with larger tensile forces (see Selection Guide, see link). Care must be taken during mounting (e.g. with epoxy) and operation because the translators are not protected by a case or preload (see mounting guidelines see link). Accessories Extension cables & connectors: see link in the "PZT Control Electronics" section. Factory Installed Options* P-702.10 High-Temperature Option (see link) P-702.20 Low-Temperature Option (see link) P-703.10 High-Vacuum Option (see link) *When ordering these options, change the last digit to 7, e.g. P-249.10 to P-249.17, and list options separately. Laser tuning Static and dynamic positioning of small parts Fiber alignment, etc For more examples see link P-249 PZTs paper clip for size comparison P-249 dimensions (in mm). See table for length, L
