In scenarios such as precise optical calibration, micro-sample angle measurement, laser optical path debugging, photoelectric sensing calibration, and university research experiments, many devices are constrained by low installation space and the need for moderate adjustment travel. They have to overcome the limitation of the small-angle platform's travel and avoid the space redundancy problem of the large-sized platform. The Sefan Optoelectronics 7SGA115 electric angular position table, as the upgraded compact angular position table of the 7SGA1 series, precisely fills the industry demand gap. With a ±15° widened adjustment travel, 50mm ultra-low axis center, and precise control performance, it becomes the preferred equipment for precise mid-range angle adjustment in narrow spaces, balancing accuracy, travel, and integration adaptability.
Compared with the conventional models of the same series, the core performance of 7SGA115 has been comprehensively optimized, achieving a golden balance between travel and accuracy. The equipment is equipped with a 252:1 precision worm gear and worm transmission mechanism, combined with the classic ring-shaped ball + ring-shaped steel guide rail structure, which operates smoothly without jamming, has precise gap control, and completely eliminates common problems such as empty return, jitter, and angle drift. Relying on the mature precision transmission system, the equipment can stably achieve continuous and uniform angle scanning and fixed-point locking, perfectly adapting to high-precision experimental scenarios such as spectral analysis, interference detection, and optical element inclination fine-tuning, ensuring the repeatability and accuracy of each set of test data.
The compact and lightweight structure is the core highlight of 7SGA115, specially designed for narrow-device integration scenarios. The equipment uses a 65×65mm standard small tabletop, suitable for the installation and fixation of various micro-optical components and small samples, while optimizing the axis height to 50mm ultra-low design, significantly reducing the overall installation height, perfectly adapting to the installation requirements of low-height cavities, compact optical platforms, and integrated detection modules, solving the problems of high axis center, large space occupation, and limited equipment stacking. The body is lightweight, compact, yet has solid rigidity, stable center load performance, and is not afraid of load pressure in daily precise testing conditions.
The control and integration performance continues the high-end standard of the series, compatible with automated experimental processes. The equipment is equipped with 42 stepper motors, combined with high-quality elastic coupling for transmission structure, with synchronous and efficient power transmission, low noise, smooth start and stop, and no precision degradation during long-term continuous operation. It is equipped with a standard DB9 communication interface, which can seamlessly match the 7SC series dedicated motion controller, supporting angle fixed-point adjustment, reciprocating scanning, timing programming, multi-axis linkage, etc., automating the process away from manual repeated fine-tuning, significantly improving the efficiency of experiments and testing.
The modular design is flexible and versatile, suitable for multi-dimensional platform construction. The equipment adopts a series of universal concentric rotation structure, and two 7SGA115 stacked orthogonally can achieve concentric dual-axis two-dimensional pitch adjustment, quickly building a high-precision dual-axis attitude control module. The tabletop is reserved with standard threaded installation holes, which can be freely combined with electric translation tables, elevating tables, and rotating tables, quickly building a multi-dimensional precise motion system, suitable for the integration transformation of various non-standard precision detection equipment and automated experimental devices.
Safety protection and durability are fully equipped, suitable for long-term scientific research conditions. The device is equipped with bidirectional limit switches, effectively avoiding the risk of overtravel impact, providing comprehensive protection for the equipment body and precision optical components; it supports optional photoelectric zero position sensors to achieve automatic zeroing upon power-on, meeting the long-term cyclic automated testing requirements. The entire machine is made of high-strength aluminum alloy material, processed by hard anodizing technology, wear-resistant, corrosion-resistant, and resistant to deformation, with outstanding rigidity, stable precision during long-term continuous operation, and suitable for various application scenarios such as university laboratories, research institutes, optical enterprises, and precision detection lines. The 7SGA115 electric angle positioner boasts three core advantages: a ±15° wider travel range, an ultra-low axis compact structure, and sub-degree-level precise angle control. It precisely covers scenarios for small and medium-sized precise attitude adjustment, releasing a larger control range within a limited space and empowering each precise test and optical path calibration with stable performance.
