quote / order

Direction of the axes and torques for linear stages

68509131, dimensions in mm

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.
