The product You were Looking for was moved Click Here for new Address P-170 P-178 Open- & Closed-Loop HVPZT Translators Displacement to 80 µm Pushing Forces to 2000 N Pulling Forces to 50 N Sub-msec Response Sub-nm Resolution Options: Vacuum, High & Low Temperature, Choice of End Pieces P-170 to 173 and P-178 PZT translators are high-resolution linear actuators for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. Standard models are specifically designed for open-loop operation. For highest accuracy, select the P-177.10 closed-loop option with integrated ultra-high-resolution strain gauge position sensors and operate with PI servo-control electronics (see "Tutorial: Piezoelectrics in Positioning" section, see link, and see link for details). P-178 models are equipped with thinner PZT ceramic layers than P-170 to P-173 models, providing more displacement in the same package. On the other hand, the "maximum" operating voltage is limited to -1000 V. Also, voltages in excess of -750 V should be applied to the P-178 models only for short durations. The PZT ceramic stack is protected by an aluminum case. The standard top piece is a magnet and the standard bottom piece is a ferromagnetic steel flat. A variety of optional top and bottom pieces are available for easy mounting. For push/pull forces up to 3 N, the translator can be mounted by clamping around the case. For larger forces, the translator must be mounted by the base. Accessories Extension cables & connectors: see link in the "PZT Control Electronics" section.
