US-Made Ultra-Precision XY Positioning Stages are available from 4x4” to 12x12” travel.

Monolithic XY positioning stages for semiconductor, metrology, optics, precision assembly, industrial applications, new from PI

AUBURN, Mass., June 3, 2025 /PRNewswire-PRWeb/ -- PI, a global leader in precision motion control and nanopositioning, now offers the US-manufactured V-781 XY Stage series, setting new standards for precision, stability, and ease of integration in high-performance motion systems. Engineered as a monolithic, single-module XY stage — rather than a stack of separate linear axes — V-781 stages deliver superior straightness, minimized yaw, and enhanced geometric stability in a compact, low-profile design. By integrating direct-drive motors, crossed roller bearings, and nanometer-resolution encoder feedback, it ensures exceptional accuracy, reliability, and long-term performance.

Key Features

  • 110x110mm, 210x210mm and 310x310mm travel ranges
  • Crossed roller bearings for ultra-smooth motion with superior load and moment capacity
  • Direct measuring linear encoders with resolution to 1nm
  • High acceleration (up to 1g) and velocity (up to 1m/s)
  • Absolute encoder option eliminates the need for homing, enhancing start-up safety and operational efficiency
  • Monolithic XY design eliminates misalignment issues common with stacked axes
  • Optimized for maximum precision and stiffness, up to 50kg load capacity
  • Lower profile with a wider bearing base for improved motion straightness and reduced pitch/yaw errors
  • Ironless direct-drive 3-phase linear motors, for cogging-free, friction-free, and backlash-free motion
  • Long service life and minimal maintenance, ideal for 24/7 industrial use
  • Pre-lubricated for lifetime performance

Performance & Integration with Advanced Motion Controllers
The V-781 offers bidirectional repeatability of ±0.07 microns and outstanding geometric accuracy in flatness, straightness, pitch, and yaw. Whether in semiconductor wafer inspection, precision metrology, or micro-assembly, it excels in applications where sub-micron accuracy and dynamic responsiveness are essential. For maximum performance, V-781 stages are seamlessly integrated with PI's A-81x series EtherCAT®-based motion controllers.

ACS-hardware based motion controllers support multi-axis synchronization and are compatible with third-party EtherCAT® equipment. Stability and dynamics can be boosted by running the optional advanced PILOT algorithms, that also reduce motor currents at the same time.

Why Choose V-781 XY Stages?
Designed for the most demanding precision automation and motion control tasks, the V-781 XY stage family integrates advanced mechanics, frictionless direct-drive technology, and advanced controller compatibility. It's the ideal solution for mission-critical applications requiring exceptional accuracy, long-term stability, and high-speed throughput.

Industries Served
Semiconductor wafer test and inspection, additive manufacturing, laser micro-processing and beam steering, photonics alignment, surface metrology and profilometry, biotech, life sciences, manufacturing, automation
