Newport XMS50-S Ultra-Precision Motorized Linear Stage 50 mm Travel
The Newport XMS50-S Ultra-Precision Motorized Linear Stage is a compact 50 mm travel member of the Newport XM-S Series, designed for demanding manufacturing, test, measurement, inspection, and precision positioning applications. The XMS50-S uses a direct-drive ironless linear motor architecture to deliver smooth, responsive motion without the backlash, hysteresis, wind-up, or stiction associated with screw-driven motion stages.
Designed for high-performance motion control environments, the XMS50-S is suitable for applications requiring accurate positioning, smooth scanning motion, and reliable operation in advanced technical workflows. Typical XM-S Series applications include semiconductor wafer inspection, direct laser lithography, sensor test and calibration, ultra-precision assembly, laboratory automation, photonics alignment, and precision metrology setups.
Features and Benefits of the Newport XMS50-S Ultra-Precision Motorized Linear Stage
The Newport XMS50-S Ultra-Precision Motorized Linear Stage provides practical value for professional users who require reliable, high-accuracy motion control in compact precision positioning systems.
- 50 mm precision travel: Provides a 50 mm travel range for compact linear positioning applications requiring high accuracy and repeatability.
- Ironless linear motor drive: Uses a center-driven, frictionless direct-drive linear motor to eliminate backlash, hysteresis, wind-up, and screw-related wear.
- Ultra-smooth motion: The ironless motor design provides zero cogging for smooth velocity control across the travel range.
- High-accuracy feedback: Uses a Heidenhain LIF 481 linear scale with 1 Vpp feedback and 4 µm signal period for precise position feedback.
- Anti-creep crossed roller bearings: High-class matched pairs of anti-creep crossed roller bearings support ripple-free motion for demanding scanning and inspection systems.
- Compact and reliable design: Electronics are attached to the stationary base, eliminating moving internal cables and improving reliability.
- ESP compatible: Designed for compatibility with Newport ESP motion systems, allowing compatible Newport controllers to recognize the stage and upload stage parameters.
Advanced Features and Practical Applications
The Newport XMS50-S is engineered for users who need the motion benefits of a linear motor stage in a compact format. Unlike conventional screw-driven stages, the XMS50-S direct-drive architecture avoids mechanical transmission limitations and provides rapid response, smooth travel, and reduced wear. This makes it well suited for production environments, inspection platforms, automated optical systems, metrology instruments, and sensitive research setups.
The stage is machined from stress-relieved 7075 aluminum for long-term strength and stability. Critical surfaces are machined and precision ground under controlled manufacturing conditions to support stage accuracy and repeatability. The XM-S Series T-shaped carriage design supports precision XY assemblies while helping maintain stage preload and robustness, making the stage more tolerant of nonideal mounting conditions than some alternative carriage designs.
The Newport XMS50-S is also designed with thermal stability in mind. The XM-S Series uses an extra-large ironless motor coil to improve efficiency and reduce heat dissipation, which is important for ultra-precision motion applications where thermal effects can limit performance. The precision aligned low-thermal-expansion linear scale is mounted near the center of the stage to help minimize temperature-related effects on repeatability and accuracy.

Installation and Compatibility Notes
To reach the published specifications, the XMS50-S stage must be fixed on a plane surface with a flatness of 5 µm. The stage is supplied without cables, and the appropriate cable kit must be ordered separately according to the Newport XPS controller configuration used. Newport specifies that XM-S Series stages operate only with cables up to 5 meters maximum.
The XMS50-S is ESP compatible, allowing compatible Newport ESP motion controllers to recognize the connected stage and upload stage parameters. The stage is also designed for use with Newport XPS Series control electronics. When used with non-Newport electronics, users are responsible for proper cable modification, sensor signal connections, and system integration.
Maintenance and Handling
The Newport XMS50-S is a precision mechanical device and should be handled carefully. The stage should be used and stored in a clean environment without dust, humidity, solvents, or other contaminants. The optical scale should be protected from contamination, and the stage should not be used in vacuum environments, high humidity, hard UV, X-ray, or other hostile environments unless specifically approved for the application.
Newport recommends returning the XM-S stage for re-lubrication after 2000 hours of use and returning the stage once per year for recalibration to its original specifications. Buyers should review condition notes, included accessories, cable availability, controller compatibility, and mounting requirements before purchase.
