Basler ace Industrial Camera High-Speed Line Scan Design Guide

In the Basler ace series of industrial cameras, the CoaXPress interface can achieve high-speed, low-latency image transmission. In addition to the external data cable, the camera also requires a high-performance transmission scheme to ensure data integrity between the sensor and the interface circuit. Among these, the extremely thin coaxial cable (micro coaxial cable) serves as a key high-speed signal transmission medium. Although its diameter is only 0.3mm to 0.5mm, it can meet GHz-level signal transmission requirements. Its performance directly determines the stability of the camera during high-speed operation.

I. Core Characteristics of Extremely Fine Coaxial Beam

The ultra-fine coaxial cable束 has an accurately controllable impedance. For high-speed signals, common requirements are 50Ω single-ended or 100Ω differential. Even minor impedance deviations can cause reflections and jitter, affecting the stability of the CoaXPress link. It has a compact structure, complete shielding layer, and can effectively reduce signal attenuation and crosstalk, while also resisting external electromagnetic interference. The small bending radius design and excellent flexibility can adapt to the internal wiring of the Basler ace compact body, and the reliable connection methods, including miniature coaxial connectors or direct welding to PCB, also ensure long-term stability.

The key points to pay attention to when selecting a wire harness

When selecting a miniature coaxial cable assembly, attention must be paid to bandwidth and frequency response, especially for CoaXPress CXP-12 with data rates up to 12.5 Gbps, which has strict requirements for low loss and high-frequency performance. Shielding and anti-interference capabilities are also crucial; choosing cables with high-density braiding or complete shielding layers can reduce EMI influence. The flexibility and durability of the cable assembly should match the camera assembly requirements to ensure no breakage or performance decline over the long term. Process compatibility is also very important, including interface type, pad spacing, and welding process temperature, to ensure assembly control.

Section 3: Application Techniques and Suggestions

In Basler ace series industrial cameras, it is recommended to prioritize high-precision impedance-controlled cables with impedance tolerance controlled within ±5%. According to the internal space design, balance the cable diameter and flexibility. Too thin cables may increase resistance and weaken shielding performance. Choose materials that can withstand high temperatures and have a long bending life to ensure long-term operational reliability. At the prototype stage, signal integrity can be verified through TDR (time-domain reflection) and S parameter analysis to ensure the stability of high-speed signal transmission within the interior, providing reliable protection for the external CoaXPress interface.

For Basler ace series industrial cameras, the extremely thin coaxial cable is not just a simple connecting component, but also a key link in the high-speed signal transmission chain. Selecting the appropriate micro coaxial cable can ensure the integrity and stability of high-speed data transmission within the camera, enhancing the camera's performance and long-term reliability.
