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

Auburn, MA — 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.

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

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.
