Precision-class Z stage
High guiding accuracy and stiffness due to ball screws and crossed roller guides. Stress-relieved aluminum base for high stability. Vacuum-compatible product variants on request. Noncontact limit and reference switches (Hall effect). Reference switch with direction sensing in the middle of the travel range.
Drive types
- .xxSD variant: 2-phase stepper motor for high torque even at low velocities and high resolution.
- .023xxx variant: DC servo motor
- .025xxx variant: Brushless DC motor (BLDC) for high rotational velocity. Smooth running and low wear, therefore longer lifetime.
Position measuring
- Versions with DC motor: Rotary encoder
- Optional: Integrated linear encoder, installed centrically.
Highly accurate position measuring with incremental linear encoder
Noncontact optical linear encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.
Minimum incremental motion and slow motion
In conjunction with an ACS controller (e.g., ECMsm-4B44T-NNNNN), versions with stepper motor and integrated linear encoder (L-310.xASD) achieve repeatable minimum incremental motion in the range of the sensor resolution. The same configuration achieves constant low velocities of a few sensor increments per second.
Application fields
Precision positioning in industry and research, high duty cycles.

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.
