M3-LS-3.4-15

Overview

The M3-LS-3.4-15 is a direct-drive piezoelectric linear smart stage with an embedded closed-loop controller, measuring 32 x 32 x 11 mm and weighing 30 grams. It provides a 15 mm travel range with 0.5 µm resolution and less than 5 µm bi-directional repeatability. The unit operates on 6 V DC, consuming approximately 5 W during motion at 4 mm/s under a 1 N load, while maintaining zero power position holding. It accepts high-level commands via I2C or SPI interfaces or through a USB adapter.

Feature Summary

• Integrated all-in-one design eliminates the need for external control boards by embedding drive electronics within the compact housing.
• Absolute encoding capability ensures precise positioning without requiring homing procedures upon power-up.
• Low-voltage operation allows integration into battery-powered devices with zero-power position holding capabilities.

Applications

• Hand-held and battery-powered instruments
• Biomedical devices
• Miniature or embedded microscopes
• Precision opto-mechanical alignment

Procurement Notes

Verify the specific model suffix to confirm the 15 mm stroke length and integrated controller configuration. Ensure the system processor supports the required I2C or SPI communication protocols for direct command input. Confirm that the 6 VDC power supply meets the typical 5 W operational requirement during movement. Check environmental constraints against the specified operating temperature range of +5 °C to +40 °C.

Selection Notes

Select this model when long 15 mm travel is required in a sub-32 mm footprint. The 1 N force output supports vertical loads up to 100 grams. Consider the quiet operation suitable for near-patient environments compared to stick-slip stages. Verify compatibility with New Scale Pathway software if PC-based development or scripting is needed for automation.

FAQ

Does the M3-LS-3.4-15 require a homing sequence?

No, the stage features absolute encoding, which eliminates the need for homing on power-up.

How is the stage controlled?

It accepts high-level motion commands directly via standard serial interfaces (I2C or SPI) or through a USB adapter connected to a PC.

What is the power consumption profile?

It consumes approximately 5 W during motion at 4 mm/s with a 1 N load, but holds position with zero power and has a quiescent draw of less than 0.2 W.
