In the precise alignment of dense optical paths, in the integrated assembly of small devices, and in the fine debugging of laboratories, the contradiction between "space limitation" and "no reduction in precision" has always troubled engineers and researchers. The heavy structure and complex operation of traditional translation stages make it difficult to meet the usage requirements of compact scenarios. Sifan Optoelectronics has been deeply engaged in precise motion control for 22 years. It has iteratively innovated based on the need for compact space and convenient debugging, and匠心crafted the 7STA10 series of electric translation stages (also known as the "Insect Series"), with "ultra-thin and compact design + nanometer-level resolution + manual and electric dual control"， becoming the optimal choice for single-axis precise displacement in space-constrained scenarios， unlocking new possibilities for precise control in compact environments.
Ultra-thin and compact black technology， saving space without sacrificing precision
Space adaptation is the core demand of compact scenarios. The 7STA10 series breaks through the bottleneck of the heavy design of traditional translation stages， adopting an ultra-thin integrated body， with an overall height reduced by 40% compared to similar products， and a weight of only 1.3-2.1kg (depending on the travel distance)， like a "insect" that is small and agile， able to easily fit into space-constrained scenarios such as dense optical paths， small automated equipment， and portable detection instruments， without requiring significant adjustments to the original layout. What's more remarkable is that the compact design does not sacrifice performance： equipped with a precision ball screw pair drive and a cross roller + finely ground V-shaped guide rail combination， the linear accuracy is excellent， even in a narrow space， it can still maintain a stable load of 10kg during high-speed reciprocating motion， completely solving the industry pain point of "difficult to accommodate high-precision equipment in small spaces".
Nanometer-level precise transmission， micro-motion controllable without deviation
Precision is the core lifeblood of precise displacement. This series is equipped with 42 stepper motors (1.8°)， combined with 8 subdivision drive technology， with a resolution of up to 0.000625mm (625 nanometers)， repeatability positioning accuracy <0.005mm， axial clearance <0.02mm， achieving nanometer-level micro-motion control. The motor and precision ball screw are connected through an imported high-quality elastic coupling， not only with synchronous transmission without delay， but also with running noise controlled below 40dB， like a whisper， perfectly adapting to scenarios sensitive to noise such as laboratories and medical equipment. A 1mm travel screw ensures smooth and uniform motion， even at an ultra-low speed of 0.001mm/s， there is no crawling phenomenon， from optical element alignment to micro-part assembly， every micro-motion is precisely controllable.
Manual and electric dual control， convenient operation with high efficiency
Convenient operation is the key to improving debugging efficiency. The 7STA10 series innovatively adopts manual and electric dual control design： equipped with an electric control module， it can be connected to the Sifan 7SC series motion controller through standard DB9/RS232 interfaces， compatible with LabVIEW， Python programming environments， supporting complex motion modes such as automatic positioning， uniform scanning， etc.， suitable for automated production lines； at the same time， it is equipped with a detachable handwheel， which can be manually finely debugged in scenarios without the need for automation， with smooth and no-jamming rotation， easily achieving micrometer-level fine adjustment. Both ends are equipped with zero position and limit switches， which not only facilitate quick reset and calibration， but also effectively avoid mechanical damage caused by exceeding the travel limit， providing dual guarantees for equipment and workpiece safety， significantly reducing the difficulty of debugging.
Flexible adaptation for all scenarios， integrated without worries about cost
Modular design gives the product super compatibility. The 7STA10 series offers three travel options of 30mm， 50mm， and 100mm (corresponding models 7STA1030/1050/10100)， with standard screw holes and through holes reserved on the tabletop， supporting various installation methods such as horizontal and vertical， directly connecting to optical platforms and small equipment racks， with integration time shortened by 50% compared to similar products. As a benchmark of domestic high-quality and cost-effective products, its total life cycle cost is 40% lower than that of imported brands. Moreover, the core components have undergone strict aging tests and have a service life of 30,000 hours, requiring no frequent maintenance or replacement.
Backed by domestic craftsmanship, it empowers various industries.
As a distinctive product in the field of domestic precision motion control, the 7STA10 series has passed the ISO9001 quality system certification. The core components offer a 3-year warranty, and the response time for after-sales service is ≤ 4 hours. With the core advantages of "saving space, high precision, and easy operation", it has been widely applied in precision optical detection, small-scale automation equipment, laboratory research, medical instruments, etc.: precisely aligning in the dense optical path of optical fibers, maintaining stable displacement in portable detection equipment, assisting in precise debugging in university research experiments, and becoming the trusted choice of the Chinese Academy of Sciences and well-known electronics enterprises.
From the integrated assembly of compact equipment to the microscopic exploration in the laboratory, the 7STA10 series of electric translation stages from Saifan Optoelectronics redefine the standard for compact scene displacement control. Choosing Saifan is choosing a displacement control partner that "does not save precision while saving space, and does not lack performance despite a small size", enabling each precise displacement to be efficiently adapted to narrow spaces and helping domestic precision equipment break through in specific fields!
