Please note that at the moment only a limited selelction of variants of this product family is available. If you require further information contact us via info@pi.ws.
Reference-class linear stage
High travel accuracy with recirculating ball bearings. Inductive limit switches. High position resolution due to incremental encoder with analog signal transmission (sin/cos, 1 Vpp). Multi-axis combinations with the directly driven rotation stages of the UPR series. Models with DC servo or stepper motors are available with the same footprint.
Magnetic direct drive
Ironless magnetic direct drive for high velocity and acceleration. High position resolution.
Application fields
Industry and research. Metrology, precision scanning in semiconductor or electronics manufacturing.

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
