X15G Datasheet

General Description

This small, inexpensive piezoelectric motor has been designed for precision and responsiveness. It has a broad, variable speed range and can operate almost noise-free.

Features

• High resolution: < 10 |jm

• Ultra light: 1.2 g

• Highly responsive: 0 to v₀ in 100 |js

• Rugged environment compatible

• Vacuum compatible
