PI (Physik Instrumente) L.P. High Linearity Piezo Stack P-405 Picoactuator

Multi-Axis Actuators with Highly Linear Displacement Lead-free, crystalline actuator material High dynamics Ideal for operation without position control Low electrical power consumption Minimal length tolerances Stack actuator Bipolar operating voltage up to ±500 V. Nearly hysteresis-free motion (<0.2 %). No creep. Picoactuators®, as longitudinal and shear actuators, are configurable up to heights of 20 mm and maximum travel ranges of ±1.5 µm. Technology Picoactuator® longitudinal and shear actuators consist of a crystalline piezoelectric material. The specific displacement for shear actuators is ±0.02 % of the actuators length and ±0.01 % for longitudinal piezo actuators. This value is ten times lower when compared to piezo actuators made of lead zirconate titanate (PZT). The motion is highly linear and almost hysteresis free.
