The ACA1600-20GM features a 1/3″ progressive scan CCD sensor with a resolution of 1.3 megapixels. Its global shutter technology captures sharp images of fast-moving objects without the rolling shutter artifacts common in many CMOS cameras. Operating at up to 30 frames per second over Gigabit Ethernet interface, this camera provides reliable performance for automated inspection systems. The color CCD sensor ensures accurate color reproduction, which is crucial for applications requiring color differentiation.
Technical specifications include a pixel size of 4.8 µm x 4.8 µm, providing good light sensitivity. The camera supports GigE Vision protocol version 1.2 and GenICam standard, ensuring compatibility with most machine vision software packages. With a spectral range of 400-1000 nm, it can be used with various lighting conditions. The compact and robust housing (29 mm x 44 mm x 85.5 mm) allows for easy integration into existing systems.
The 1/3″ sensor format used in the ACA1600-20GM offers a practical balance for many applications. Compared to a 1/1.8″ sensor with 2 MP resolution, the larger sensor provides approximately 70% more surface area. This allows for either larger pixels (better light sensitivity) at the same resolution or higher resolution with similar pixel sizes. However, the 1/3″ sensor keeps the overall system more compact and cost-effective, especially when considering lens selection and pricing for different sensor formats.
Global shutter technology, whether operating at 20fps or 30fps, provides the crucial benefit of capturing distortion-free images of moving objects. The ACA1600-20GM’s 30fps capability offers a 50% higher frame rate compared to 20fps alternatives, allowing for inspection of faster processes or providing more image samples for analysis. However, for applications where speed is less critical, a 20fps camera with similar specifications (like a hypothetical 1/1.8″ 2 MP CCD Mono GigE camera) might offer cost savings while still providing the essential global shutter advantage.
The choice between color and monochrome cameras depends on application requirements. The ACA1600-20GM’s color CCD sensor is ideal for applications requiring color differentiation, such as food sorting, pharmaceutical verification, or electronics inspection where color markings are important. In contrast, a monochrome CCD camera (like a 1/1.8″ 2 MP model) typically provides higher spatial resolution (since no color filter array is needed) and better light sensitivity. For measurements based on contrast or texture without color information, monochrome often performs better.
Color cameras excel in applications where color is a key differentiator: ripe vs. unripe fruit detection, correct labeling of colored packages, verification of LED colors, or inspection of multi-colored components. Monochrome cameras are preferred for dimensional measurement, surface defect detection, high-speed scanning, or any application where maximum light sensitivity or spatial resolution is paramount. The ACA1600-20GM’s color capability makes it versatile for applications that may require both grayscale and color analysis.
The GigE Vision interface offers significant advantages for industrial applications. Standard Ethernet cables are cost-effective, readily available, and allow for longer cable lengths compared to USB 3.0. Power-over-Ethernet (PoE) support enables both power and data transmission over a single cable, simplifying installation. The networked architecture facilitates easy integration of multiple cameras and centralized control, making the ACA1600-20GM ideal for complex vision systems spanning large areas.
Compared to USB 3.0, GigE offers superior cable length and networking capabilities. Compared to Camera Link, it provides lower cost and easier installation. For systems requiring multiple cameras—whether all of the same model like the ACA1600-20GM or mixed with other types like a 1/1.8″ 2 MP Mono camera—GigE’s network-based architecture allows flexible deployment using standard network switches. This makes the ACA1600-20GM suitable for both standalone installations and as part of larger multi-camera vision systems.
Typical applications include semiconductor inspection, where color fidelity and defect detection are critical. In automotive manufacturing, the ACA1600-20GM can be used for part verification and assembly validation. The food and beverage industry utilizes it for sorting products by color and detecting contaminants. Medical device manufacturing benefits from its precise imaging for quality control. The GigE interface makes it particularly suitable for distributed systems in large facilities like warehouses for logistics and package tracking.
Application-specific selection involves trade-offs. For color-critical tasks, the ACA1600-20GM is superior to monochrome alternatives. For ultra-high-speed applications (>60fps), CMOS-based cameras might be better despite potential rolling shutter issues. For maximum resolution in a similar price range, a 2 MP monochrome camera could be considered. The ACA1600-20GM’s strength lies in providing good color performance at a reasonable frame rate with the reliability of global shutter and GigE connectivity.
Compared to Hikrobot’s similar offerings, Basler cameras like the ACA1600-20GM generally command a premium due to their proven reliability, extensive documentation, and global support network. FLIR cameras might offer higher frame rates with CMOS sensors but may compromise on color accuracy or global shutter performance. IDS cameras are known for innovation and flexibility but can be more expensive. For budget-conscious projects requiring reliable color imaging, the ACA1600-20GM presents a balanced value proposition.
The market offers various CCD GigE camera options. Compared to a hypothetical 1/1.8″ 2 MP monochrome CCD GigE camera at 20fps, the ACA1600-20GM offers color capability and higher frame rate (30fps vs 20fps) but lower resolution (1.3MP vs 2MP) and smaller sensor size. Price differences reflect these trade-offs: monochrome cameras typically cost less than color versions with otherwise similar specifications. The choice ultimately depends on whether color information or higher spatial resolution is more valuable for the specific application.
Successful integration requires proper network planning. Use high-quality Cat6 or Cat6a cables with shielded connectors in electrically noisy environments. A PoE (Power over Ethernet) switch can simplify wiring by providing power through the Ethernet cable. Basler’s Pylon software development kit includes drivers, tools, and sample code compatible with common vision libraries like OpenCV, HALCON, and LabVIEW. For optimal performance, ensure the host computer’s network adapter supports jumbo frames and has sufficient processing power for image analysis tasks.
Additional components include appropriate lens mounts and filters to optimize imaging conditions. For the ACA1600-20GM’s 1/3″ sensor, C-mount lenses with appropriate image circle coverage are required. If integrating with other camera types (like a 1/1.8″ sensor camera), note that lens requirements differ. Protective enclosures may be necessary for harsh environments. Basler’s pylon Viewer software provides convenient camera configuration and testing during setup. Regular network maintenance ensures consistent performance over time.
