The Primatics PLR110 rotary stage is engineered for applications where precise angular positioning, fast settling, and installation flexibility are critical. Its direct-drive brushless servo motor eliminates the mechanical limitations of worm-driven systems, providing smoother motion, lower wear, and greater long-term reliability.
Designed with a large open aperture and low-profile footprint, the PLR110 gives engineers the flexibility to route cables, optics, or pneumatic lines directly through the center of the stage. This makes it especially useful in compact automation systems, optical alignment platforms, and assembly environments where space efficiency matters.
With angular resolution down to 0.43 arc-seconds and repeatability of ±2 arc-seconds, the PLR110 is built for high-accuracy positioning tasks that require stable and repeatable motion over time.
Ideal Applications:
- Optical component alignment
- Precision assembly systems
- Semiconductor inspection tools
- Laser processing systems
- Automated metrology stations
- Motion platforms for research and development
Features
PLR110 Rotary Stage Features
Unlike gear-driven rotary stages, the PLR110 uses a direct-drive motor architecture, reducing backlash and minimizing mechanical wear. This improves precision and extends service life.
Large Hollow Bore Design
The open-center design simplifies cable management and enables clean routing for wiring, vacuum lines, and optical paths—valuable in automation and photonics applications.
Low Profile for Tight Installations
At only 38 mm tall, the PLR110 fits into space-restricted systems without sacrificing performance.
High Repeatability for Process Stability
Consistent motion performance helps maintain alignment accuracy across repeated cycles, reducing variation in automated processes.
Factory-Tested Accuracy
Every stage undergoes verification testing and burn-in procedures before shipment, helping ensure long-term consistency and dependable field performance.
