In the precise positioning of vertical assembly, in the smooth feed during high-altitude detection, and in the heavy-load operations with multi-axis collaboration, "prioritizing safety and accuracy" is the core proposition of precise motion control. When traditional electric translation stages are used vertically, there are common problems such as slipping and dislocation due to power failure, which have become safety hazards in high-end manufacturing and scientific research experiments. Saifan Optoelectronics has been deeply engaged in precise motion control for 22 years. It has iteratively innovated based on the vertical heavy-load and safety protection requirements, and匠心crafted the 7STA09C series of electric translation stages. With "power failure self-locking protection + micrometer-level precise transmission + full-scenario adaptability"， it has become a safe and reliable choice for single-axis displacement control， laying a solid safety defense line for industrial manufacturing and scientific research innovation.
Power loss self-locking advanced technology, ensuring greater peace of mind during vertical heavy loads.
Safety protection is the core requirement in vertical scenarios. The 7STA09C series innovatively incorporates an integrated brake-equipped 57-step motor. In the event of motor power failure or system emergency stop, the built-in braking mechanism immediately locks itself, firmly securing the position of the screw, completely eliminating the risks of sliding or falling during vertical use, providing dual protection for high-value workpieces and operators. Combined with a high-quality ball screw (with a pitch of 5mm) installed with three bearings, the transmission rigidity is significantly improved. Even when carrying heavy loads, it can effectively suppress the screw's movement, achieving a repeatability positioning accuracy of ±0.005mm and a positioning error control within ±0.01mm, providing "no offset under heavy load, no displacement under power failure" dual guarantees, and perfectly adapting to high-risk scenarios such as vertical assembly and high-altitude detection.
Precise transmission system, stable and efficient dual online operation
Precision and stability stem from the robust technical architecture. This series adopts precise linear slide rail guidance, ensuring smooth and uninterrupted movement with no stalling. The carrying capacity is enhanced by 30% compared to traditional rails. Even under long-term high-speed reciprocating motion, the tabletop jitter remains below 1μm. The motor and screw are synchronized through high-quality elastic coupling, which not only keeps the operating noise below 45dB, but also eliminates transmission delay. The no-load speed can reach 500mm/s, significantly improving the production line cycle and experimental efficiency. The body is made of high-strength aluminum alloy and is formed as a single piece through precise processing and anodizing treatment. It is lightweight yet highly rigid, capable of resisting vibration and moisture in complex industrial environments. The core components have a lifespan of 30,000 hours, which is 50% higher than the industry average, reducing long-term maintenance costs.
Flexible adaptation across all scenarios, seamless integration for greater efficiency
The modular design endows the product with extremely strong compatibility. The 7STA09C series offers a full range of travel options from 50mm to 600mm (including models such as 7STA0950C/150C/400C/600C), with standard threaded holes and through holes reserved on the tabletop. It supports various installation methods including horizontal, vertical, and inverted installation, and can be easily integrated into automated production lines, laser processing equipment, multi-axis experimental platforms, and other scenarios. The standard DB9 interface is equipped, allowing for direct connection to the Sefan 7SC series motion controller. It is compatible with LabVIEW and Python programming environments, supporting complex motion modes such as point storage and uniform scanning. Without the need for professional programming knowledge, it can be quickly debugged. Zero and limit switches are built-in at both ends, which not only facilitate precise reset but also effectively prevent mechanical damage caused by excessive travel, further enhancing the safety of equipment usage.
Domestic craftsmanship endorsement, empowering thousands of industries and sectors
As a benchmark product in the domestic field of precision motion control, the 7STA09C series has obtained ISO9001 quality system certification. The core components come with a 3-year warranty, and the response time for after-sales service is ≤ 4 hours. With the core advantages of "safety + accuracy + durability", its total life cycle cost is 35% lower than that of imported brands. It has been widely applied in semiconductor packaging, new energy equipment assembly, precision optical detection, university research experiments, etc.: ensuring positioning accuracy in OLED panel vertical evaporation, achieving smooth movement in wafer inspection equipment, eliminating safety hazards in high-altitude component assembly, and becoming the preferred choice of the Chinese Academy of Sciences and well-known manufacturing enterprises.
From the safe and efficient operation of industrial production lines to the precise exploration in laboratories, the Sefan Optoelectronics 7STA09C series of electric linear translation stages, with its core advantages of "power failure self-locking, micrometer precision control, and full-scenario compatibility", has redefined the standard for vertical heavy-load displacement control. Choosing Sefan is choosing a displacement control partner that is "safe and reliable, precise and efficient", ensuring that every linear movement is both safe and precise, helping domestic precision equipment break through in the global market!
