P-820 Small-Load Open-Loop Piezoelectric Translators (LVPZT)
P-820 Small-load piezoelectric translators are high-resolution linear actuators for static and low-frequency dynamic applications. They provide sub-millisecond response and sub-nanometer resolution.
Design
Mounting
Application examples:
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.
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.
