PU 40 – Description

The PU 40 consists of only one metallic part that allows for excellent mechanical stability and the ability for it to work dynamically.

This translation stage shows a nearly linear motion by an applied voltage signal from -20 up to 130 V.

This stage can be combined for X, Y, Z 3D motion systems. The basic flexure stage is equipped with the threads for mounting. Each piezo system is supplied with the necessary screws and parts for a multi-axis configuration.
