| | | ■ Displacement to 45 urn ■ Pushing Forces to 50 N ■ Pulling Forces to 10 N ■ Sub-msec Response ■ Sub-nm Resolution ■ Options: Ball Tip P-820 Small-load piezo translators are high-resolution linear actuators for static and low-frequency dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. Design The translators are equipped with highly reliable multilayer PZT ceramic stacks protected by a non-magnetic stainless steel case with internal spring preload. The standard translator tip is a stainless steel flat. Select the P-820.95 ball tip option to help decouple off- | | |
| | | axis and torque loads from the translator. Mounting For push/pull forces up to 3 N the translator can be mounted | | |
