In the limited working area of the compact optical experimental platform, in the embedded displacement module of the precision instrument, and in the micro-element alignment scenarios in the narrow space, many users have encountered dilemmas: large travel translation stages are too large to fit, and micro-manual displacement stages cannot achieve automated precise control. In the past, to simultaneously achieve small size, large load, and micrometer-level accuracy within a 25mm short travel, they often had to custom-order special models at high prices, which not only had high costs but also long delivery periods.
Safin Optoelectronics, with 22 years of expertise in the field of precision opto-mechanics, precisely targeted the industry pain points of small-space precision displacement and launched the 7STA1325 compact electric translation stage. With a "super small body + 5kg heavy-load capacity + micrometer-level precision" hard-core combination, it broke the stereotype that "small volume equals low load and low precision", providing a high-performance and cost-effective standardized solution for compact precision scenarios.
Ultra-closed design, easily embedded in narrow working areas
The internal space of many precision devices is extremely limited, and even a few extra millimeters of body thickness may cause the entire integrated solution to get stuck. The 7STA1325 maximized the "space utilization" from the very beginning. The body adopts an ultra-thin integrated structure, and the overall volume is much smaller than that of conventional translation stages in the same category. The effective travel of 25mm fully covers the conventional requirements for short-distance precision displacement and can easily fit into compact experimental platforms, portable detection equipment, and small optical adjustment frames that traditional electric translation stages cannot accommodate.
Standard installation holes are reserved on the side of the body, which can be directly horizontally fixed on the optical platform, or support various installation methods such as vertical and inverted, without the need for additional custom adapter plates. It can be quickly embedded in the narrow space of existing equipment, and many users have tested that replacing the original manual displacement stage with it, without making significant modifications to the original equipment structure, can complete the automated upgrade in just a few hours, significantly shortening the project renovation period.
Small body hides great rigidity, stable as a rock with 5kg heavy load operation
Many compact translation stages, in order to reduce volume, have to sacrifice structural rigidity. Even with a little additional weight, the structure will deform, causing the operation to be sluggish and shaky, and it is impossible to guarantee precision. The 7STA1325 fits a precise ball screw and linear slider guide rail combination in a super small body, combined with the fixed support structure at both ends, fundamentally avoiding the screw creep and structural deformation under heavy load.
The center load can reach 5kg, which is at the industry-leading level among compact electric translation stages, and can stably carry small optical lenses, spectrometer probes, micro tooling fixtures, etc. During full-load operation, the platform jump is still less than 1μm, and even with continuous high-frequency reciprocating operation, there will be no common problems of stalling or drift in ordinary micro translation stages, fully meeting the requirements of long-term stable operation.
Micrometer-level precise control, achieving ultra-high positioning performance in short travel
Short travel displacement is more sensitive to positioning accuracy. Even a small error will directly affect the final experimental data and product yield. The 7STA1325 is equipped with a high-precision stepper motor, with a transmission process without delay, and the repeat positioning accuracy can reach ±0.003mm, with a resolution as high as 0.000625mm. Within the full travel range of 25mm, each step displacement is precisely controllable.
Whether it is the sample scanning feed of a compact spectrometer, the sub-millimeter alignment of micro optical components, or the precise detection movement of small semiconductor devices, it can steadily output consistent high-precision performance, completely saying goodbye to the errors and efficiency bottlenecks of manual adjustment, allowing displacement control in small spaces to also achieve automation and high precision. The equipment is equipped with standard communication interfaces, which can seamlessly adapt to the entire series of Sefan motion controllers. It supports multi-axis linkage and point programming functions, and can easily integrate into mainstream automation programming environments such as LabVIEW and Python. Even with no prior knowledge, it can be quickly debugged.
Nowadays, 7STA1325 has been widely applied in compact scientific research equipment, portable optical detection instruments, micro-component precision assembly and many other scenarios. With its unique advantages of "small size, large load capacity and high precision", it has become the preferred displacement solution for many scenarios with limited space. As the benchmark product of Sefan's compact product line, its core components have all undergone strict aging tests and support a 3-year core component warranty and a 4-hour rapid response local after-sales service. There is no need for a long waiting period for customization, and standardized spot goods can solve the big problem of precise displacement in small spaces.
Small size, big achievements. The 7STA1325 compact electric translation stage, with 22 years of precise motion control technology, integrates micro-meter-level stable control into a very small body, allowing every displacement requirement of each narrow workstation to find a reliable and convenient standardized solution.
