L-306 Compact Precision Z Stage
Compact Design, Multi-Axis Combinations
- Compact design: Surface 63 × 63 mm
- Stepper motors and closed-loop DC motors
- Optional: Linear encoder for direct position measuring
- Crossed roller guides
- Noncontact reference and limit switches
Compact Z stage, versatile in use
Z stage with compact size due to folded drive with belt gears. Fits onto linear stages with M6 50 mm × 50 mm connection grid (e.g., L-406).
Drive
- 2-phase stepper motor or closed-loop DC motor
- Backlash-compensated ball screws
Position measuring
- Incremental linear encoder (optional with stepper motor variants)
- Noncontact optical reference and limit switches
Highly-accurate position measuring with incremental linear encoder
Noncontact optical linear encoders measure the position with highest accuracy directly on the platform Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.
Crossed roller guide
For crossed roller guides, the point contact of balls in ball guides is replaced by the line contact of hardened rollers. Consequently, they are considerably stiffer and need less preloading, which reduces friction and enables smoother running. Crossed roller guides are also characterized by high guide accuracy and load capacity. Force-guided rolling element cages prevent cage creep.

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.
