The product You were Looking for was moved Click Here for new Address P-820 Small-Load Open-Loop LVPZT Translators Displacement to 45 µm Pushing Forces to 50 N Pulling Forces to 10 N Sub-msec Response Sub-nm Resolution Options: Ball Tip P-820 Small-load PZT translators are high-resolution linear actuators for static and low-frequency dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. 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. Due to the small dimensions of the PZT ceramics, P-820 translators are sensitive to bending and lateral forces. Select the P-820.95 ball tip option to help decouple off-axis and torque loads from the translator. 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. For positioning of magnetic parts the P-176.30 Magnetic Adapter can be glued onto the translator tip.
