Piezoelectric translators are solid­state ceramic actuators which con­vert electrical energy directly into linear motion (mechanical energy) with virtually unlimited resolution.

PI offers a comprehensive assort­ment of high-resolution piezo actu­ators and drives for industrial and scientific applications. In addition to the hundreds of models presented in this catalog, PI can also deliver custom designs. By virtue of its highly vertical structure, PI is able to control each step-from the man­ufacture of the piezoelectric raw materials, sensor and servo-control technology, to final testing of the complete systems.
