ZOLIX RS Series Integrated Linear Motorized Translation Stage (Industrial Grade)

Overview

The ZOLIX RS Series Integrated Linear Motorized Translation Stage is an industrial-grade precision motion solution engineered for high-cycle, space-constrained automation environments requiring sub-micron repeatability and long-term mechanical stability. Based on Couette-type linear guidance architecture with an integrated R-profile rail, the stage eliminates traditional external guide rail assemblies—reducing profile height to under 20 mm while maintaining structural rigidity and load-bearing integrity. Its core motion principle relies on precise rotary-to-linear conversion via a preloaded, 1 mm pitch imported ball screw driven by a bipolar 2-phase stepper motor (Sanyo Denki STP-28D1003-0805), enabling deterministic open-loop positioning without encoder feedback. Designed explicitly for OEM integration into optical alignment systems, semiconductor handling modules, micro-positioning test fixtures, and compact metrology platforms, the RS Series conforms to fundamental mechanical metrology requirements defined in ISO 230-2 (determination of positioning accuracy and repeatability) and supports traceable calibration protocols per ISO/IEC 17025 when used within accredited laboratory workflows.

Key Features

• Monolithic R-type linear rail structure fabricated from hardened SUS440 stainless steel—offering exceptional torsional stiffness (>1.2 × 10⁵ N·mm/rad), corrosion resistance, and dimensional stability across thermal gradients from 15 °C to 35 °C.
• Preloaded Ø6 mm ball screw with 1 mm lead and ground P3-class accuracy—ensuring minimal axial play (10⁶ operational cycles.
• Integrated opto-mechanical home and limit sensing: Three externally mounted SHARP GP1S092HCPI photointerrupters (origin + dual end-of-travel) provide TTL-compatible NPN outputs compliant with IEC 61000-4-2 ESD immunity standards.
• Modular cabling architecture using HEYER high-flex shielded cable (UL AWM 20276, 200,000 bend cycles @ ±90°), terminated with keyed DB9 male connectors—eliminating strain-induced signal degradation during dynamic operation.
• Standardized mechanical interfaces: 4×M3 threaded holes on platform surface (40×40 mm and 60×60 mm variants), compatible with industry-standard kinematic mounts, lens holders, and fiber alignment stages.

Sample Compatibility & Compliance

The RS Series accommodates payloads ranging from bare optical components (e.g., MEMS mirrors, collimators, fiber ferrules) to assembled sub-assemblies weighing up to 8 kg horizontally. Its low-profile form factor (≤20 mm total height) enables vertical stacking in multi-axis goniometers or integration beneath objective lenses in confocal or Raman microscope stages. All materials comply with RoHS Directive 2011/65/EU and REACH Annex XVII restrictions. Mechanical performance data—including unidirectional accuracy (<20 µm), repeatability (<±3 µm), and motion straightness (<10 µm)—are validated per ISO 230-2 Annex D procedures using laser interferometry (Keysight 5530 system). No lubricants requiring periodic replenishment are used; the stainless steel rail and ball screw assembly operates dry or with solid-film MoS₂ coating for maintenance-free service life exceeding 2 years at 10 Hz continuous cycling.

Software & Data Management

While the RS Series operates natively in open-loop mode via standard step/direction signals, it is fully compatible with ZOLIX’s optional ZMotion Control Suite (v3.2+), which provides GUI-based trajectory planning, real-time position logging (CSV/TXT export), and synchronization with external triggers (TTL/USB). The suite supports scripting via Python API (zolix-motion-sdk) for automated calibration routines and integrates with LabVIEW™ (NI-VISA drivers included) and MATLAB® (Instrument Control Toolbox). Audit trails, user access levels, and parameter change logs meet GLP/GMP documentation requirements per FDA 21 CFR Part 11 when deployed with optional digital signature modules and time-stamped database storage.

Applications

• Precision optical path length adjustment in tunable laser cavities and interferometric sensors.
• Automated focus scanning in compact OCT probe heads and miniature endoscopic imaging systems.
• Wafer-level alignment during pick-and-place operations in micro-opto-electro-mechanical systems (MOEMS) packaging lines.
• Dynamic sample positioning in benchtop XRD and FTIR spectrometers where footprint minimization is critical.
• Calibration reference stage for verifying resolution and linearity of vision-based metrology tools (e.g., machine vision gauges, profilometers).

FAQ

Is encoder feedback available as a factory option?
No—encoder integration is not supported due to the stage’s ultra-thin mechanical architecture; however, closed-loop performance can be achieved externally using third-party linear encoders mounted on custom adapter plates.
What is the maximum allowable ambient temperature for continuous operation?
The stage is rated for continuous use between 15 °C and 35 °C; operation above 40 °C requires derating of load capacity by 15% per 5 °C increment.
Can the RS Series be operated vertically without additional braking?
Yes—the holding torque (78.5 mN·m) exceeds gravitational torque for the maximum specified vertical load (4 kg), eliminating need for external brakes under static or low-acceleration conditions.
Are CAD models and mounting templates provided?
Yes—STEP and IGES files, along with PDF mechanical drawings and hole pattern templates, are supplied with every order and accessible via ZOLIX’s secure customer portal.
Does the stage support vacuum environments?
Not natively—the standard HEYER cable and SHARP sensors are rated for atmospheric use only; vacuum-compatible variants (CF flange mount, ceramic-insulated cabling, and UHV-rated sensors) require custom quotation.
