In the precise alignment of optical detection, in the efficient feeding of automated production lines, and in the precise adjustment of scientific research experiments, "stable and reliable linear displacement" is the core foundation that guarantees efficiency and accuracy. The common problems such as positioning deviation, high-speed jitter, and installation limitations that are prevalent in traditional translation stages have become obstacles for the upgrade in the precision field. Sefan Optoelectronics has been deeply engaged in precision motion control for 22 years. Based on market pain points, it has iteratively upgraded and meticulously crafted the 7STA01B series of electric translation stages. With "imported-level transmission accuracy + strong load stability + full-scenario adaptability", it has become the preferred solution for single-axis displacement control, enabling efficient operation in scientific research and industrial scenarios.
Imported-level transmission, micrometer-level precise positioning
Precise transmission is the core competitiveness of translation stages. The 7STA01B series is equipped with imported high-quality ball screws, combined with three-bearing installation and shaft-end locking structure, which fundamentally eliminates screw loosening. The repetitive positioning accuracy is up to ±1μm, and the positioning error can be controlled within ±5μm, ensuring precise and consistent high-speed reciprocating motion. The precision linear bearing guide rail adopts a two-end support design, with an intermediate suspended structure that makes the movement smoother. Even in vertical installation scenarios, it can achieve stable displacement, solving the problem of vertical use of traditional translation stages causing stalling and accuracy degradation. The stepper motor is synchronized with the ball screw through an imported elastic coupling, not only with a noise level lower than 45dB, but also with no transmission delay. From optical element alignment to precise part processing, each displacement is precisely in place.
Combining rigidity and flexibility, stable and efficient dual lines
Breaking the "impossible to achieve both high precision and high speed" curse, the 7STA01B series achieves a comprehensive balance in performance. The high-strength aluminum alloy body is combined with an optimized mechanical structure, with a maximum load capacity of up to 50kg. Even when equipped with heavy detection equipment or processing fixtures, the platform jump is still <1μm, meeting the heavy-load requirements of automated production lines. Equipped with high-performance stepper motors, the free-speed can reach 500mm/s, combined with intelligent drive algorithms, the acceleration is smooth without impact, significantly shortening production line cycle and experimental period. The XY axis is equipped with a stainless steel dust-proof cover, and the Z axis can be selected with a fan-shaped cloth protection, effectively isolating dust and oil stains. In laboratory clean environments and complex industrial workshop conditions, it can achieve 30,000 hours of trouble-free operation, with the lifespan of core components being 50% higher than the industry average.
Flexible adaptation, seamless integration in all scenarios
With a modular design, it adapts to diverse needs. The 7STA01B series demonstrates strong compatibility. The travel range covers 10mm-500mm, the platform is reserved with standard threaded holes and through holes, supporting horizontal, vertical, and inverted installation methods, easily integrating into optical instruments, automated production lines, scientific research platforms, etc. The standard DB9 and RS232 interfaces can be directly connected to Sefan's 7SC series motion controllers, compatible with LabVIEW and Python programming environments, supporting point storage, uniform scanning, etc., and can be quickly debugged and used without professional programming knowledge. It also supports replacing with servo motors, customizable for high-speed or heavy-load configurations, achieving full-scenario coverage from scientific research experiments to industrial mass production, with system integration time shortened by 40% compared to similar products.
Domestic craftsmanship, empowering thousands of industries
As a benchmark product in the domestic precision motion control field, the 7STA01B series has passed ISO9001 quality system certification, with core components providing a 3-year warranty, and the response time for after-sales service is ≤4 hours. Thanks to its high cost-effectiveness advantage, its total life cycle cost is 35% lower than that of imported brands. It has been widely applied in fields such as optical inspection, semiconductor packaging, automated production lines, and research laboratories. It ensures assembly accuracy in optical lens assembly, improves yield in wafer inspection, and optimizes fixture positioning in mold processing. It has become the preferred choice for the Chinese Academy of Sciences and well-known manufacturing enterprises.
From the cutting-edge exploration in laboratories to the large-scale manufacturing on production lines, the 7STA01B series of electric linear translation stages from Saifan Optoelectronics have redefined the standard for single-axis displacement control with their core advantages of "precision, stability, flexibility, and durability". Choosing Saifan is choosing a reliable partner for displacement control, making each linear movement a double guarantee of efficiency and accuracy, and helping domestic precision equipment break through in the global market!
