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, "safety and accuracy are equally important" has always been the core proposition of precise motion control. The traditional electric translation stage, when used vertically, often encounters problems such as slipping and dislocation due to power failure. These are persistent safety hazards hanging over users in high-end manufacturing and scientific research experiments. After 22 years of deep research in the field of precise motion control, Sevan Optoelectronics has iteratively innovated based on the core needs of vertical heavy-load and safety protection,匠心 crafting the 7STA09C series of electric translation stages. With the core advantages of "power failure self-locking protection + micrometer-level precise transmission + full-scenario adaptability"， it becomes a safe and reliable choice for single-axis displacement control， firmly building a safety defense line for industrial manufacturing and scientific innovation.
The black technology of power failure self-locking makes vertical heavy-load scenarios more reassuring
Safety protection is the primary demand in vertical operation scenarios. The 7STA09C series innovatively integrates an integrated brake 57-step motor. When the motor loses power or the system is suddenly stopped， the built-in braking mechanism immediately triggers self-locking， firmly locking the screw position， completely eliminating the risks of slipping or falling during vertical use， providing dual safety guarantees for high-value precision workpieces and on-site operators.
Combined with the high-quality ball screw with three bearings installation， the 5mm lead design significantly improves the transmission rigidity. Even when carrying heavy loads， it can effectively suppress the screw's movement， with a repeat positioning accuracy of ±0.005mm， and the positioning error is firmly controlled within ±0.01mm， truly achieving "no offset under heavy load， no displacement under power failure"， providing a dual guarantee for high-risk scenarios such as vertical assembly， high-altitude detection， and heavy-load hoisting. No longer need to worry about the problem of workpiece damage and equipment collision caused by sudden power failure.
Precise transmission architecture， stable and efficient dual online
Precision and stability always stem from the support of a hardcore technical architecture. This series adopts a precise linear slider guide rail for guidance， ensuring smooth and uninterrupted movement throughout the process， with a 30% direct increase in carrying capacity compared to traditional guides. Even under long-term high-speed reciprocating motion， it can maintain a stability of less than 1μm in platform jitter.
The motor and screw are synchronized through a high-quality elastic coupling， not only controlling the running noise below 45dB， but also achieving transmission without delay， with a no-load speed of up to 500mm/s， significantly improving production line rhythm and experimental efficiency. The body is made of high-strength aluminum alloy through one-piece molding， undergoes precise processing and anodizing treatment， and at the same time has the characteristics of lightweight and high rigidity. It can resist vibration and moisture in complex industrial environments， with a core component lifespan of up to 30，000 hours， 50% higher than the industry average， significantly reducing long-term maintenance costs.
Flexible adaptation in all scenarios， system integration is convenient and efficient
The modular design gives this product strong scene compatibility. The 7STA09C series offers a full range of 50mm to 600mm travel options， covering all scenarios from short-distance precise positioning to large-surface heavy-load displacement. The platform is reserved with standard threaded holes and through holes， supporting horizontal， vertical， and inverted installation methods， and can be easily integrated into various systems such as automated production lines， laser processing equipment， and multi-axis experimental platforms.
Standard DB9 interface is provided， which can directly connect to the Sevan 7SC series motion controller， compatible with mainstream programming environments such as LabVIEW and Python， supporting complex motion modes such as point storage and uniform scanning， allowing ordinary engineers to quickly complete debugging without deep professional programming knowledge. Both ends of the equipment are equipped with zero position and limit switches， which not only facilitate precise reset but also effectively avoid mechanical damage caused by exceeding the travel limit， further enhancing the equipment's safety， making system integration worry-free and hassle-free throughout the process.
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. Now, it has been widely applied in semiconductor packaging, new energy equipment assembly, precision optical detection, university research experiments, and many other fields: firmly maintaining positioning accuracy in OLED panel vertical evaporation, achieving smooth movement in wafer inspection equipment, completely eliminating safety hazards in high-altitude component assembly, and becoming the trusted choice of the Chinese Academy of Sciences and many well-known manufacturing enterprises.
Self-locking and precise control without boundaries. The 7STA09C series of electric linear translation stages from Saifan Optoelectronics, with its core advantages of "power failure self-locking, micrometer precision control, and full-scenario compatibility", redefines the industry standard for vertical heavy-load displacement control. Choosing Saifan is choosing a "safe and reliable, precise and efficient" displacement control partner, making each linear movement both safe and precise, and helping domestic precision equipment break through the global market with stability.
