In precision optical testing, automated precise inspection, new material research, and high-end scientific research experiments, small travel displacement stages often fail to meet the requirements of large sample testing, wide-range optical path calibration, and heavy-load equipment mounting. To have a longer effective travel, higher carrying capacity, while maintaining micrometer-level precise positioning and operational stability, has become the core demand for many scientific and industrial precise operations. Saifan Optoelectronics has deeply specialized in the field of precise displacement control and has launched the 7SAA501 electric combined displacement stage. With a modular three-axis design for large travel, a high-load rigid structure, and ultra-low error precise control, it fills the gap in medium and large-range multi-dimensional precise displacement, becoming the core equipment for medium and large-scale precise positioning.
New three-axis combined architecture, wider travel compatibility for more operation scenarios
The 7SAA501 electric combined displacement stage is specially designed for medium and large-range precise displacement scenarios. It adopts a standardized modular combined design, integrating three 7STA03100 precise electric translational stages with a dedicated right-angle mounting plate for one-piece assembly. It can stably achieve full three-axis automatic three-dimensional translation, completely solving the problems of insufficient travel for conventional small displacement stages and limited adaptability to working conditions. The equipment has a 100mm ultra-large standard effective travel, which doubles the displacement regulation range compared to conventional 50mm travel displacement stages, and can easily meet the complex requirements of wide-range optical path debugging, large workpiece alignment, large-area sample scanning, and multi-interval dynamic displacement testing.
The overall assembly process is precise and rigorous, with high joint accuracy and extremely low coaxiality error. The integrated rigid structure eliminates the problems of loosening and deviation during long-term operation. The机身 layout is compact and regular， expanding the travel range without redundancy or bulkiness， and balancing space utilization and equipment compatibility. It can be quickly integrated into precision experimental platforms， automated inspection equipment， and optical-electromechanical integrated testing systems， suitable for fixed positions and dynamic debugging in various operation modes.
Heavy-load precision structure， stable load and high precision dual online
The 7SAA501 does not sacrifice precision for large travel， nor does it reduce stability for high load. These are its core core advantages. The equipment is equipped with imported precision ball screw and high-precision linear slider guide rails. Through pre-tightening the gap to eliminate process optimization， the transmission is smooth without jamming， with minimal friction loss. Combined with the elastic coupling synchronous transmission design， the operation noise is low， the dynamic response is fast， and the overall displacement regulation is uniform and precise. Relying on mature photoelectric zero position calibration technology and dual-end limit protection switches， the equipment's repeat positioning accuracy is stable and meets the requirements， with micrometer-level error controllable. It maintains precise operation throughout long-term high-frequency reciprocating operation， eliminating drift deviation.
The机身 adopts a high-strength aluminum alloy reinforced structure design， with excellent rigidity and excellent resistance to deformation， possessing outstanding heavy-load carrying performance. It can stably carry heavy optical lenses， precise detection modules， and large experimental fixtures， without fear of vibration and displacement deviation under heavy-load conditions. At the same time， the equipment's detail configuration is fully equipped. In vertical operation scenarios， a power-off protection device can be selected for use， effectively avoiding power-off settlement and displacement deviation problems； standardized universal installation holes are compatible with various supporting equipment， making installation and debugging simple and convenient， significantly reducing system integration and later maintenance costs.
