The actual application of HD-BNC connector in frame grabber mainly solves two major technical pain points: interface density and transmission rate. Compared with the traditional BNC interface, its compact design can increase the number of channels by 30%-50% on the same panel area, which is particularly important for intelligent quality inspection equipment that needs to connect more than 8 cameras at the same time. In terms of transmission performance, the interface supports the 12G-SDI standard, with a theoretical bandwidth of up to 12 Gbps, and can losslessly transmit 4K@60fps industrial camera data streams to meet the needs of high-precision scenarios such as semiconductor inspection.
The application characteristics of industrial sites determine that interface reliability is crucial. The patented locking structure of HD-BNC can withstand 15G acceleration shock in vibration testing, and the plug-in life exceeds 5,000 times, which is nearly 3 times higher than that of ordinary BNC interfaces. It is worth noting that although the interface appearance has changed, it can still be compatible with the existing BNC cable system through a customized impedance matching adapter (75Ω±1%), which is of great value to equipment upgrade and transformation projects. Actual measured data shows that when using an HD-BNC image acquisition card to transmit 4096×3000@120fps images, the bit error rate can be controlled below 1E-12, which plays a decisive role in ensuring the accuracy of the defect detection algorithm.
