The SCA640-74FC represents a pinnacle in high-speed industrial imaging, incorporating the renowned Sony ICX204 CCD sensor to deliver exceptional color fidelity. This camera is engineered specifically for automated environments where consistency and low noise levels are critical for successful image analysis. Its robust housing and professional-grade internal components ensure reliable operation even in challenging factory conditions worldwide.
Technical specifications for the SCA640-74FC include a pixel size of 9.9 µm x 9.9 µm, which is significantly larger than standard sensors, providing extraordinary light-gathering capabilities. The camera utilizes a CCD sensor with Color Global Shutter technology, ensuring that all pixels are exposed simultaneously to prevent motion blur. This hardware configuration is ideal for high-speed conveyor lines where spatial accuracy is paramount for rejection mechanisms or sorting tasks.
In addition to its sensor capabilities, the SCA640-74FC features digital I/O ports that allow for precise synchronization with external lighting or triggering devices. This level of hardware-based control ensures that image acquisition is perfectly timed with the movement of the production line. When integrated with proper lighting solutions, the camera can capture high-contrast images that simplify the work of vision software algorithms.
The CCD sensor technology inside the SCA640-74FC provides a superior signal-to-noise ratio, ensuring that color data remains pure even in lower light conditions. Unlike rolling shutter sensors, the global capture prevents the color “bleeding” effect often seen with moving objects. This makes the camera a dependable choice for industries that require high-confidence color grading, such as food processing or pharmaceutical verification.
Stability in color reproduction is a hallmark of Basler’s CCD implementation, which utilizes advanced internal calibration algorithms to maintain white balance across varying temperatures. This means that a vision system calibrated in the morning will produce identical results throughout the shifts. Such consistency reduces the need for frequent recalibration, thereby increasing overall equipment effectiveness (OEE) in a professional manufacturing setting.
ความสำคัญของ Color Global Shutter ต่อความแม่นยำ
ระบบ Color Global Shutter ในอุปกรณ์ตัวนี้ช่วยขจัดปัญหา “Rolling Shutter Effect” ที่มักทำให้ภาพวัตถุที่เคลื่อนที่เร็วเกิดอาการเอียงหรือบิดเบี้ยว การจับภาพวัตถุแบบหยุดนิ่งสนิทในทุกเฟรมภาพช่วยให้การคำนวณตำแหน่งทางเรขาคณิตทำได้อย่างแม่นยำ ซึ่งเป็นหัวใจสำคัญของงานประเภทคัดแยกสินค้าความเร็วสูงที่ต้องการความผิดพลาดเป็นศูนย์
By capturing the entire frame at once, the global shutter in the SCA640-74FC ensures that dimensions within the image represent the true physical size of the object. In robotics and high-speed sorting, even a few pixels of distortion can lead to mechanical errors. This camera provides the geometric integrity needed for precise coordinate mapping, making it an essential tool for high-end automation projects requiring 79 fps throughput.
High-speed color imaging requires significant bandwidth, but the architecture of the SCA640-74FC is optimized to handle these data streams with minimal latency. This allows for real-time decision-making in rejection systems, where the vision computer must decide within milliseconds whether to accept or reject a part. The combination of color accuracy and temporal precision makes this model a formidable asset in modern industrial quality assurance.
The IEEE 1394b interface used in the SCA640-74FC provides a deterministic data transfer protocol, which is vital for time-critical vision tasks. Unlike some modern consumer interfaces, Firewire-b ensures that data packets are delivered with guaranteed timing, allowing for perfect synchronization across multi-camera setups. This makes it an ideal choice for systems that rely on legacy hardware but require updated imaging performance from Basler.
Compatibility with standard industrial Firewire controllers allows the SCA640-74FC to be integrated into existing machines without major overhauls of the network infrastructure. This reduces the total cost of ownership for manufacturers looking to upgrade their visual inspection capabilities. Basler’s Pylon SDK provides the necessary software support to manage these connections easily, offering a unified driver set that simplifies the development of custom vision applications.
While Hikrobot provides cost-effective alternatives, they often utilize CMOS sensors which may not offer the same level of color uniformity as the SCA640-74FC’s CCD sensor in specific lighting conditions. FLIR and IDS also offer high-quality cameras, but Basler’s market-leading Pylon software suite and localized technical support in Thailand provide a significant advantage for system integrators. Choosing this model ensures a balance between upfront investment and long-term operational success.
In summary, the SCA640-74FC provides a future-proof foundation for high-speed color vision tasks, combining the best of Sony CCD technology with the reliable Firewire-b interface. Its ability to produce crisp, high-contrast images makes it a standout performer in the VGA-resolution class. By investing in this hardware, you are ensuring that your machine vision system is equipped with the best-in-class tools for years to come.
