MLT Series Low-Profile High-Precision Linear Motor Stages

The MLT Series of compact, low profile, high precision linear stages bridges the ultra-precision performance of the XM family and the compact VP family of linear stages. These stages showcase the latest innovations and expertise of MKS in precision stage design for various Industrial applications, while keeping the short setups expected of motion products when used with MKS motion controllers.

The MLT stages are ideal for typical scanning or point to point applications in semiconductor, industrial or research markets for metrology, sensor test and calibration, alignment and pick-and-place assembly.

Compact, low profile, high repeatability design
Stiff, FEM-optimized aluminum body prevents thermal bending effects
Precision crossed roller bearing slides provide accurate linear motion
Plug and Play - ESP compatible
Easy to build multi-axis configuration

Features

Reliable Design

Built with high strength aluminum alloy, the base of each MLT stage is optimized with Finite Element Method (FEM) for highest rigidity and best thermal performance. Select components like long life and high load crossed roller bearings, high force linear motors and high precision linear encoders are added with not only performance, but also reliability in mind. Built in limit switches prevent over travel and collision. Significant tests were conducted to ensure the high reliability performance of the MLT.

Ironless Motor

MLT series stages are equipped with MKS designed ironless motors that include hall effect sensors and thermistor in a very compact size. Compared to iron core motors, the main advantage of ironless motors is better speed stability (no cogging) and shorter settling time, which is critical for fiber alignment applications.

Low Cost of Ownership

MLT series compact, low profile and fast stages utilize less space, operate with higher accelerations and speeds, reducing operating costs. Also, due to their high reliability design they require low initial investment and need less maintenance.

XY and XYZ Configurations

The MLT can be built into XY and XYZ stacks utilizing the available mounting holes. A magnetic shield is required between the X and Y stages. Cable chains can also be supplied as needed. Pre-assembled XYZ stacks are available in the short travel ranges. The MLT-Z stage features a magnetic counterweight to accommodate a range of vertical loads, while maintaining excellent positioning performance.

Plug and Play ESP Compatible

The MLT is compatible with XPS series standard MKS controllers that support plug and play ESP technology, making startup really easy without the need for complex driver configuration. (Note that for XY configurations, manual parameter setting is required.)
