Piezoelectric translators are solid-state ceramic actuators which convert electrical energy directly into linear motion (mechanical energy) with virtually unlimited resolution.
Quality and Selection
PI offers a comprehensive assortment of high-resolution piezoelectric 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.

- Large force generation (up to 50,000 N and more)
- Microsecond-range response
- No backlash, stiction or friction
- Immune to magnetic fields
- Extremely low steady-state power consumption
- No wear and tear
- Vacuum and clean-room compatibility
- Operation at cryogenic temperatures possible
