Preloaded Open- & Closed-Loop Extra-High-Load HVPZT Translators

 

The product You were Looking for was moved Click Here for new Address P-243 P-247 Preloaded Open- & Closed-Loop Extra-High-Load HVPZT Translators Displacement to 120 µm Pushing Forces to 30000 N Pulling Forces to 3500 N Extremely High Stiffness Options: Vacuum, Low & High Temperature, Water-Resistant P-243 and P-247 preloaded extra-high-load PZT translators are high-resolution linear actuators for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. The high load capacity and internal spring preload makes them ideal for machining applications and vibration cancellation. 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 for operation with PI servo-control electronics (see "Tutorial: Piezoelectrics in Positioning" section, see link, and see link for details). P-247 models are equipped with thinner PZT ceramic layers, providing more displacement than P-243 models in the same package. On the other hand, their "maximum" operating voltage is limited to -1000 V with voltages in excess of -750 V recommended only for short durations. Models P-247.xx, P-243.30 and P-243.40 come with a stainless steel case with internal spring preload protecting the PZT ceramic stack. Models P-243.10 and P-243.20 come with an aluminum case, stainless steel end pieces and spring bolts providing the preload. Factory Installed Options* P-177.10 Closed-Loop Option, Strain Gauge Sensors, see link P-702.10 High-Temperature Option (see link) P-702.20 Low-Temperature Option (see link) P-703.20 High-Vacuum Option (see link) P-706.00 Water-Resistant Case (not for P-243.10 and .20, see link) * When ordering these options, change the last digit to 7, e.g. P-243.10 to P-243.17, and list options separately.
