Product Description

Series R ring actuators consist of a large number of contacted ceramic discs. Compared with a tube actuator, the ring actuator reaches a higher stiffness and the expansion is twice as high.

Series R piezo actuators are without casing, and without a pre-load. They are only connected at the ceramic top and ground plate. These ring actuators (without a pre-load) should not be used in dynamic applications.

Series R actuators are for open-loop systems only.

Please ask for a screwing top plate for easy mounting of mirrors.

FAQ

How do I choose between open-loop and closed-loop versions?

Choose closed-loop when you need absolute positioning accuracy and repeatability (e.g. measurement, alignment). Open-loop is more cost-effective and responds faster when you only need relative fine motion or scanning, or when your system already has its own feedback.

Can I test the unit before deciding?

Nahshon is the exclusive distributor of piezosystem jena in Taiwan and keeps commonly used demo units available for scheduled testing, with Chinese-language selection support and direct access to factory engineering.

How do I confirm pricing and lead time for Series R?

Add Series R along with your stroke, load and accuracy requirements to your inquiry list, and we'll help confirm the selection and reply with the factory quote and lead time.
