Description
Precision, stability and ease of use for high volume product applications
The M3-LS-U2 Linear Smart Stage is a direct-drive, high- precision micro stage built for fast, simple integration into miniature OEM systems. All drive and control functions are embedded into the compact stage assembly – no external electronics are needed!
The stage drive is a UTAF2 piezo motor combined with a 0.5
mm resolution sensor for precise, repeatable positioning of optics, probes, sensors and more. The piezo motor operates at 5 VDC. No high voltage boost is needed. Absolute encoding removes the need to home the stage on power-up, eliminating errors and disruptions in processes and experiments.
At 35 mm/sec it is 7x faster than other M3 Smart Stages.
The anodized aluminum stage uses linear ball bearing races with very low uniform friction. The bearings directly support the motor preload which creates a stable, precise and zero clearance guide system. The base is the maximum footprint required for installation in your product because the carriage moves within the total length of the base.
This smart stage is designed for long life and is ideal for embedding precision motion into high-volume products.
