The product You were Looking for was moved Click Here for new Address P-239 Preloaded Open- & Closed-Loop HVPZT Translators Displacement to 180 µm Pushing Forces to 4500 N Pulling Forces to 500 N Sub-msec Response Sub-nm Resolution Options: Vacuum, Low- & High-Temperature P-239 preloaded PZT translators are ultra-high-resolution linear actuators for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. The internal spring preload makes them ideal for machining applications. 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-239 models are equipped with thin PZT ceramic layers, providing displacement up to 180 µm at -1000 V operating voltage. For maximum lifetime, voltages in excess of -750 V should be applied only for short durations. The PZT ceramic stack is protected by a stainless steel case with internal spring preload. The standard translator tip and base have tapped holes. Select the P-239.95 ball tip option to help decouple off-axis and torque loads from the translator. For push/pull forces up to 5 N, the translator can be mounted by clamping around the case. For larger forces, the translator must be mounted by the base.
