Miniature linear positioning stages are just 75mm wide

03 November 2011

Aerotech's new MPS75SL series miniature linear positioning stages are just 75mm wide and available in four travel ranges from 25mm to 100mm. Aimed at laboratory applications that require precision alignment, or for assembly, test and measurement in industrial production environments, the small footprint and low-profile MPS75SL is available in a choice of standard precision or with Aerotech's HALAR linear error-corrected certified precision.

Standard precision is +/- 4 microns whilst HALAR calibrated accuracy is +/-1.5 microns for the 100 mm travel version, with bi-directional repeatability of +/- 0.75 microns. For motion control flexibility the MPS75SL is available with a choice of brushed DC motor or open loop stepper motor, both offering a linear positioning resolution to 0.1 microns.

Although small in size the MPS75SL has a 15 kg direct load rating which allows a practical offset  load factor thanks to the choice of crossed roller bearings. This is particularly important for maintaining high stiffness in multi-axis configurations which are made straightforward by direct carriage to stage body mounting for X-Y set-ups and optional right-angle L-brackets for vertical Z-axis mounting; as well as breadboard mounting plates for customer work piece clamping. All multi-axis configurations are available in a choice of XY, XZ or YZ orthogonal precision to 5 or 10 arc-sec. A bellows protection cover option is also available.

The new stages are a part of a complete family of MPS (Miniature Positioning Stage) motorised positioners that include linear, rotary, goniometer, and vertical lift and Z stages. Also recently launched, the new MPS50SL linear stage has a similar construction to the larger MPS75 stage but its width is just 50 mm with travel range of 25 mm or 50 mm. The motor and configuration options are also similar and the stage can be directly mounted to the MPS75 for even more space-saving potential.

As with many of Aerotech's precision positioning mechanics, the MPS range is available with optional high-vacuum preparation to 10-6 torr where modified materials, surface preparation, hardware venting, lubrication and other features can be modified for applications within vacuum chambers for  manufacturing, inspection, and military/aerospace use.

Aerotech can deliver complete motion solutions – assembled and fully calibrated with controllers set-up and ready to deliver results from the start. All equipment is fully documented with performance and calibration data, detailed operation manuals and wiring diagrams. Comprehensive technical support with optional training and on-site assistance further reduces commissioning time to ensure minimum customer learning curve and fastest time to market.

Motion controls that complement the MPS family include PC based software-only or hardware based rack or desk mount packages combining advanced motion and machine control commands that are designed to optimise performance, speed set-up times, increase throughput and enable higher quality finished parts or test quality. A wide choice of programming options include RS-274 G-code, AeroBasic, IEC61131-3, Microsoft .NET Framework and LabVIEW for varying levels of  advanced software and analytical functionality.
