The MLT250 is a low-profile linear stage with 250 mm travel, built with a high-strength 7075 aluminum base and anti-creep crossed roller bearings. It uses a 3-phase ironless linear motor with a direct-read optical encoder (20 µm signal period). Maximum speed is 0.5 m/s, acceleration is 0.5 g, and continuous force is 3 N. Load capacity is 70 N horizontally. Bi-directional repeatability is ±0.15 µm, accuracy is ±3 µm, straightness is ±5 µm, flatness is ±10 µm, yaw is ±150 µm, and pitch is ±200 µm over 80% of travel. Built-in limit switches prevent overtravel. Dimensions are 200 mm × 310 mm × 12.99 mm. It supports XY and XYZ stacking, includes grounding, and is compatible with XPS controllers using plug-and-play ESP. MTBF is 20,000 hours at 100% load and 60% duty cycle.
The MLT250 is a 250 mm travel stage designed with FEM-optimized base for the highest rigidity and thermal performance, using a high strength and stable aluminum alloy. Select components like long life and high load recirculating ball bearings, high force linear motors and high precision linear encoders are added with not only performance, but also reliability in mind. Significant tests were conducted to ensure the high reliability performance of the MLT. Built in limit switches prevent over travel and collision.
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.
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.)
