In routine precision operations such as plane optical path calibration, sample plane positioning, precise component alignment, and two-dimensional scanning detection, many debugging errors stem from unstable equipment operation, large return gap, and poor repetitive positioning. Complex multi-axis equipment has excessive functions and high costs, while ordinary simple displacement tables have insufficient accuracy and stability, making it difficult to meet the regular precision fine-tuning requirements. To address the urgent need for high-precision, high-stability, and universal displacement control in two-dimensional planes, Sefan Optoelectronics has launched the 7SAA203 electric combined displacement table. With a dual-axis integrated precision architecture, a 25mm standard practical stroke, and high-stability transmission performance, it is suitable for most two-dimensional precision fine-tuning scenarios and is a cost-effective main model for general laboratory debugging and lightweight equipment integration.
Dual-axis integrated precision architecture, universal stroke adaptation for all scenarios
The 7SAA203 electric combined displacement table adopts a mature modular dual-axis combination scheme, which is precisely assembled by two high-precision and lightweight electric translation tables to achieve X and Y two-dimensional automatic synchronous electric translation. It focuses on precise positioning in the plane dimension and does not require redundant axis functions. The equipment is compatible with precise and efficient scenarios, with a 25mm standard practical stroke, balanced and delicate interval regulation, perfectly adapting to sample plane fine-tuning, two-dimensional optical path alignment, micro-component alignment, multi-point plane scanning, and routine experimental calibration, completely solving the industry pain points of redundant equipment selection, cumbersome debugging, and poor adaptability.
The entire machine adopts an integrated compact and streamlined structure, with high assembly fit and excellent axis coaxiality. It avoids common gap errors, deviation, and non-synchronization problems of split-type equipment from the root. The body structure is solid and stable, compact and does not occupy experimental space, balancing stability and adaptability flexibility. Standardized base installation holes are标配ed， which can quickly adapt to various optical platforms， experimental fixtures， microscopes， and lightweight automation systems， ready for immediate use without complex debugging， suitable for various scenarios such as daily research and teaching， precision experiments， and small-scale production line integration.
High-stability precise transmission， zero deviation for reciprocating fine-tuning positioning
Stable and repeatable precision is the core competitiveness of 7SAA203. The equipment is equipped with precise ball screw and high-precision linear guide rails， optimized through professional pre-tightening and gap elimination processes， completely eliminating fine-tuning problems such as transmission jamming， low-speed jitter， and return gap. The transmission is smooth and uniform， with rapid and sensitive response. The micro-stepping feed of the equipment is highly controllable， whether for slow fine-tuning or high-frequency reciprocating positioning， it can maintain uniform and precise displacement， running continuously without deviation or drift， firmly adhering to the micrometer-level precise positioning standard， ensuring the consistency of each experiment and test data.
The equipment is equipped with a universal DB9 interface， which can seamlessly match the 7SC series dedicated motion controller， supporting programmatic， automated， and digital precise control， allowing for free setting of running speed， positioning points， and displacement intervals， converting traditional manual debugging uncertainty into standardized and replicable precision operation processes. It is equipped with dual protection structures of photoelectric zero position calibration and double-end limit positioning， effectively avoiding overtravel loss， positioning errors， and other problems. The equipment operates safely and durably. The body is made of high-strength aluminum alloy material， treated with anodizing process， resistant to vibration， deformation， and wear， suitable for long-term adaptation to laboratory normal conditions and mild industrial precision operations， with overall stable and reliable performance.
