Product Details Supplier Info More products

Piezomove lever-amplified piezo actuators from PI are available with various levels of integration for OEM customers, providing a cost-effective solution for reliable precision positioning.

Offering up to 500 um of travel, these actuators are suited to a variety of applications – including dispensers, valves for microdosing devices and pumps in medical technology and biotechnology – and can be customised to suit individual requirements.

The Piezomove series offers response time of a few milliseconds and, with the option of sub-nanometre resolution, can be used for static and dynamic applications, such as cavity tuning in laser optics and microscanning imaging.

For enhanced precision, optional strain gauge sensors (SGS) improve linearity up to 99.8 per cent and there is a range of controllers to ensure the optimum combination of performance and cost for individual applications.

PICMA multilayer actuators, from subsidiary company PI Ceramic, provide the driving force behind PiezoMove actuators, and feature full ceramic encapsulation for improved reliability.

The multilayer construction of these actuators provides protection from humidity and current leakage, increasing durability.

This proven design is used in biometrics, medical engineering and image processing.

PI is a global manufacturer of high precision positioning systems and products based on piezo technology. Used in markets as diverse as biotechnology, semiconductor, defence and astronomy, PI’s products work to improve the speed and precision of many cutting edge processes. Actuators, sensors and positioning systems with either sub-micron or nanometre level precision; many customised for the end user, are included in the product range.

With manufacturing and subsidiary offices around the world and a workforce of more than 500 PI provides direct local support where it is needed. Products range from component level piezo ceramic assemblies to six axis hexapod positioning robots. PI manufactures its own piezo ceramic material including multilayer devices that incorporate its patented ceramic insulation technology. Lead free ceramic technology is now also included in the company’s product range. With the flexibility and continuity of supply offered by having control of piezo ceramic production comes security and speed of delivery for customers who rely on or are looking to move into this area of technology. PI’s piezo ultrasonic and step drive motor technologies offer unique performance including self-locking capability, high force or high speed and non-magnetic and vacuum compatibility.
