ZOLIX TBX Series Compact Industrial Electric Linear Translation Stage

Overview

The ZOLIX TBX Series Compact Industrial Electric Linear Translation Stage is an engineered solution for precision linear motion in space-constrained optical and automation environments. Based on the principle of rotary-to-linear conversion via a precision ground lead screw coupled with crossed roller bearing guidance, the TBX stage delivers high positional fidelity, mechanical stability, and repeatable sub-micron motion control. Designed explicitly for integration into OEM instrumentation—such as compact spectrometers, fiber alignment systems, micro-optical benches, and automated inspection platforms—the TBX series balances dimensional efficiency (compact footprint, low mass), cost-effectiveness, and metrological robustness. Its self-locking capability—derived from the 1 mm pitch lead screw geometry and low-friction bronze nut interface—enables reliable static load retention in vertical (Z-axis) configurations without auxiliary braking mechanisms, aligning with safety-critical positioning requirements in industrial and laboratory settings.

Key Features

• Compact form factor (standard widths from 40 mm to 60 mm) optimized for multi-axis stacking and confined optical path layouts.
• Crossed roller linear guide system providing high rigidity, moment-load resistance, and consistent travel accuracy across full stroke (up to 50 mm).
• Precision ground 1 mm pitch stainless steel lead screw with tin bronze anti-wear nut—engineered for >10⁶ cycles under rated load with minimal backlash (<2 µm).
• Hard-anodized aluminum alloy body (6061-T6) offering superior thermal stability (CTE ≈ 23.6 × 10⁻⁶ /°C), corrosion resistance, and surface hardness (>HV300).
• Standard two-phase hybrid stepper motor (NEMA 11 or 14 footprint) delivering 200 full steps per revolution; compatible with microstepping drivers for interpolated resolution down to 0.1 µm.
• Externally mounted photoelectric home and limit switches (three-channel: +limit, –limit, home) with IP54-rated housings and high-flex, torsion-resistant cable assemblies (UL-certified, 10M+ flex cycles).
• Modular cabling architecture enables rapid field replacement and simplifies system-level EMC shielding integration.

Sample Compatibility & Compliance

The TBX stage supports payloads up to 5 kg in horizontal orientation and 3 kg in vertical orientation while maintaining ≤±1.5 µm repeatability over its operational lifetime. It is compatible with standard optical mounting interfaces (e.g., M3, M4 tapped holes on top plate and base) and integrates seamlessly with common motion controllers (e.g., Thorlabs KDC101, Newport ESP300, or custom PLC-based systems). While not certified to ISO 9001 at the component level, ZOLIX manufacturing adheres to ISO 9001:2015 processes, and the TBX series conforms to RoHS Directive 2011/65/EU and CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage safety (EN 61000-6-2/6-3). For GMP/GLP environments requiring audit trails, optional encoder feedback kits (incremental quadrature, 1000 CPR) are available to support closed-loop operation compliant with FDA 21 CFR Part 11 data integrity principles when paired with validated controller firmware.

Software & Data Management

The TBX stage operates natively with industry-standard motion control protocols including RS-232 ASCII commands and USB virtual COM port emulation. Native driver support is provided for LabVIEW™ (NI-VISA), MATLAB® (Instrument Control Toolbox), and Python (PySerial + custom ZOLIX API). Optional ZOLIX MotionStudio software offers GUI-based jog/positioning, waveform generation (sine, trapezoidal, custom profiles), and real-time position logging with timestamped CSV export. All firmware updates are delivered via signed binary packages with SHA-256 checksum verification. Audit logs—including command history, error codes, and motor current diagnostics—are retained in non-volatile memory for traceability during equipment qualification (IQ/OQ/PQ).

Applications

• Precision fiber optic coupling and active alignment in telecom transceiver assembly lines.
• Z-axis focus adjustment in compact confocal microscopy modules and laser-induced breakdown spectroscopy (LIBS) sample stages.
• Multi-axis scanning platforms for hyperspectral imaging systems where volume and weight budgets are restrictive.
• Automated calibration stations for photonic integrated circuit (PIC) test fixtures requiring micron-level probe positioning.
• Miniaturized environmental test chambers integrating in-situ optical monitoring via motorized translation of sensor heads.

FAQ

Is the TBX stage suitable for vacuum environments?
No—standard TBX units are rated for ambient air operation only. Vacuum-compatible variants (with dry-lubricated bearings and outgassing-tested materials) are available under custom order (ZOLIX part prefix “TBX-VAC”).
Can I replace the standard stepper motor with a servo motor?
Yes—the mechanical interface follows NEMA 11/14 standards, and the lead screw coupling is adaptable to servo motors with matching shaft diameter and keyway. Electrical integration requires external servo drive and encoder feedback loop configuration.
What is the maximum continuous operating temperature?
The stage is rated for continuous operation between 5 °C and 40 °C. Prolonged exposure above 45 °C may accelerate lubricant migration from the bronze nut and affect long-term repeatability.
Does the TBX series support homing routines with absolute position recovery after power loss?
Not inherently—the standard version uses relative homing via photoelectric switch detection. Absolute position recovery requires optional incremental encoder feedback and controller-side position tracking with battery-backed RAM or non-volatile storage.
Are CAD models and mounting templates available?
Yes—STEP, IGES, and PDF mechanical drawings (including tolerance stack-ups and hole patterns) are provided free of charge upon request through ZOLIX Technical Support portal.
