Jiangxing (Taiwan) MMT40 Motorized Linear Translation Stage

Overview

The Jiangxing (Taiwan) MMT40 motorized linear translation stage is a high-precision, compact electromechanical positioning module engineered for demanding optical alignment, interferometry, microscopy integration, and photonics assembly applications. Based on a crossed-roller bearing guide rail and C7-grade precision ground ball screw drive mechanism, the MMT40 delivers repeatable sub-micron positioning accuracy and long-term mechanical stability under continuous bidirectional motion. Its modular design supports integration into multi-axis kinematic systems—including XY, XYZ, or XZθ configurations—while maintaining orthogonal alignment integrity. The stage operates via standard two-phase stepper motor control (200 steps/rev base resolution), compatible with open-loop and closed-loop controller architectures per IEC 61800-3 EMC and safety guidelines. Designed for laboratory and OEM environments, the MMT40 conforms to ISO 9001-certified manufacturing practices at Jiangxing’s Taiwan facility and meets RoHS 2015/863/EU material compliance requirements.

Key Features

• Crossed-roller linear guide rails ensure low friction, high rigidity, and minimal wobble (< ±1.5 µm straightness over 40 mm travel)
• C7-grade ground ball screw with anti-backlash nut assembly provides positional repeatability of ±0.5 µm (typical)
• Integrated stepper motor (NEMA 17 footprint, 1.8° step angle) with optional encoder feedback interface for closed-loop operation
• Compact profile: 40 mm travel length, 80 × 80 mm base footprint, 25 mm height (excluding motor)
• Metric mounting holes (M3 and M4) on top and base surfaces enable rigid coupling to optical breadboards, cage systems, or custom fixtures
• Rated load capacity: 5 kg axial static, 2 kg dynamic (at 10 mm/s max velocity)
• Operating temperature range: 10–40 °C; relative humidity ≤ 80% non-condensing

Sample Compatibility & Compliance

The MMT40 is optimized for use with standard optical components including mirrors (up to Ø50 mm), lens mounts, fiber collimators, and piezo-driven tip/tilt platforms. Its low-profile architecture allows direct integration beneath inverted microscope objectives or within confocal scanning housings. The stage complies with ISO 10110-7 (optical component mounting interfaces) and meets mechanical interface specifications outlined in ANSI/OEOS-1-2021 for laboratory motion hardware. As a component-level device, it does not carry standalone CE or FDA certification but is intended for incorporation into systems subject to full regulatory validation (e.g., GLP-compliant optical metrology setups or ISO 13485 medical device test benches). All materials comply with EU REACH Annex XVII restrictions and are traceable via batch-lot documentation provided upon request.

Software & Data Management

The MMT40 is fully compatible with industry-standard motion control ecosystems. It supports ASCII-based RS-232 communication (9600 bps, 8N1) for point-to-point positioning and linear interpolation via STPHP-1/2 series microstepping controllers. For advanced trajectory planning—including circular interpolation, homing sequences, and limit-switch-triggered emergency stop—the CTC-2 Series dual-channel closed-loop controller offers LabVIEW™ and C# API support with real-time encoder feedback (20,000 counts/rev resolution). All controllers implement audit-trail-capable command logging, consistent with 21 CFR Part 11 electronic record requirements when deployed in regulated QC/QA environments. Firmware updates and configuration files are managed through vendor-provided Windows-based utility software with exportable CSV position logs.

Applications

• Precision alignment of laser diodes, spatial light modulators (SLMs), and fiber-optic couplers in free-space optical benches
• Z-axis focus adjustment in automated fluorescence microscopy systems requiring < 100 nm step resolution
• Dynamic sample scanning in Raman spectroscopy stages where thermal drift compensation is critical
• OEM integration into optical coherence tomography (OCT) reference arms and adaptive optics wavefront correction loops
• Calibration fixture actuation for photonic integrated circuit (PIC) wafer probing stations

FAQ

What is the maximum achievable resolution with microstepping enabled?

With STPHP-2 controller firmware and 16× microstepping, the effective step resolution is 0.01125° per pulse, translating to ~12.5 nm linear displacement per step (based on 4 mm/rev lead screw pitch).

Can the MMT40 be operated in vacuum environments?

No—standard configuration uses lubricated steel-on-steel contact surfaces and non-vacuum-rated stepper motor windings. Vacuum-compatible variants (with dry-film lubrication and ceramic bearings) are available upon special order.

Is backlash compensation supported in firmware?

Yes—CTC-2 Series controllers include programmable backlash compensation tables editable via GUI or API, adjustable in 0.1 µm increments.

What is the warranty coverage and service policy?

Jiangxing provides 24-month limited warranty covering material and workmanship defects. Field-replaceable motor and screw assemblies are stocked by authorized distributors for < 5-business-day turnaround.

Are CAD models and dimensional drawings available?

Yes—STEP and IGES format 3D models, along with GD&T-specified 2D engineering drawings (ASME Y14.5-2018), are available under NDA from the distributor’s technical portal.
