Once upon a time, if someone had told us that artificial intelligence would be operating on factory floors, traffic cameras, and inside self-driving cars, we might have said "someday". And now "that day" has arrived. We have seen AI computing move from the comfort of cloud servers to the chaos of edge equipment in a challenging transition.
When AI step out of the constant temperature and humidity data center and enter the real environment of factories, streets and vehicles, all the rules change. Suddenly, the biggest challenge is no longer AI algorithms or processing power, but those that should ensure that all components can still communicate properly under vibration, temperature fluctuations, humidity and dust.Connector。
This is not only an engineering problem, but has become a key factor in the success or failure of the entire product line: how to maintain the stability of high-speed connections when nature does its best to destroy the connection?
The current market data is impressive. According to MarketsandMarkets forecasts, the marginal AI market will grow at an annual rate of 23%, from $15.4 billion last year to $38.5 billion in 2029. But more critically, IDC found that by 2026, 3/4 enterprise data processing will be done at the edge, rather than in distant clouds.
The reason driving this shift is simple-delay is fatal. When a self-driving car needs to decide whether to brake in 10 milliseconds, or a factory robot needs to adjust its grip in real time, a cloud delay of a few hundred milliseconds is an eternity.
The problem is that edge devices often end up in environments that are least friendly to sophisticated electronics: parking lots, factory floors, moving vehicles. These environments test connectors in a way that servers in office cubicles never imagined.
Automotive industry
The number of AI modules required for Level 3 and Level 4 autonomous vehicles has increased from 3-5 three years ago to 15-20 today. Each module requires significant bandwidth, pushing vehicle data requirements to close to 25 Gbps. This is a massive flow of data in an environment that is constantly vibrating, heating, cooling, and often hostile to electronics.
Industrial environment
The industrial sector is equally unfriendly. The ABI Research found that 35% of industrial devices now have built-in edge AI, which is expected to reach 60% within three years. These are not machines that operate in a comfortable office-they operate in a dusty, oily, vibrating environment, and the staff is not always gentle with electronic equipment.
Smart City
More than 1000 cities around the world are launching smart city projects, with eight out of 10 using edge AI. This means that thousands of AI processors are running outdoors, dealing with the challenges that weather, vandalism, and urban environments can pose.
I can't count the number of times I 've heard someone in a conference say "AI works perfectly, but…" and the next word is always "connector". It's not how sophisticated connector technology is-they're actually quite straightforward. The problem is that when they are placed in an unfriendly environment, the failure rate is too high.
A common scenario: factories spend millions deploying AI quality control systems. All is well in the testing phase. Three months after production, the vibration caused the connector to loosen and the entire production line was shut down. Or outdoor surveillance cameras-after a year of normal operation, due to the decline in waterproof performance, moisture enters the connector, and suddenly they become expensive paperweights.
According to our experience, in harsh environments, connector problems account for 30-40% of all system failures. It's not a rounding error-it's a business issue.
Most connector failures are not dramatic. They do not stop working directly and flash red error messages. Instead, they create strange intermittent problems that drive engineering teams crazy.
Imagine this: Your AI system looks normal, but occasionally receives corrupted image data or sensor readings that jump for no apparent reason. Your team spends weeks troubleshooting software errors, tuning algorithms, and running hardware diagnostics. Eventually, someone discovered that a seemingly intact connector had a microscopic connection problem.
The cost of diagnosis alone is usually 20-30 times the cost of the connector itself. When this happens in a deployed system, you face field service calls, downtime, and customer questions about product reliability.
There is an old saying in the industry: "Don't just look at the price-look at the total cost of ownership". A connector that costs 20% more but can run trouble-free for five years is far better than a cheap product that may keep you busy.
The contradiction between latency and bandwidth
AI inference requires end-to-end latency of less than 10 ms while processing 4K/8K video streams. This puts very high demands on the signal integrity of the connector, especially during high-frequency transmission.
Environmental tolerance limitOutdoor applications face a temperature range of -40°C to 85°C, and industrial environments also increase vibration, shock and corrosive gases. Many standard connectors fail within a year under these conditions.
Rising power density: The new generation of AI chips consumes hundreds of watts of power, requiring connectors to carry both high-speed signals and large currents. Thermal management is a key challenge.
Maintenance Cost Considerations: Edge devices are often deployed in remote or hard-to-access locations. Once the connector fails, the repair cost may exceed the value of the equipment several times.
In edge AI design, connector selection should be divided into two categories-external I/O interfaces and internal high-speed interconnects-each corresponding to different functional and environmental resistance requirements.
External I/O Rugged Connectivity Solution
External I/O rugged connections include all connector types that directly interface with the external environment and interact with external devices or systems, including the M12 connector commonly found in industrial automation, waterproof USB Type-C for outdoor applications, and FAKRA/Mini-FAKRA RF interfaces dedicated to automotive communications.
M12 reinforced: With IP67/IP68 protection grade, quick lock or thread design, can withstand continuous vibration and impact. Ideal for industrial automation and outdoor edge AI.
Waterproof USB Type-C: Reach IP67/IP68 waterproof standard, support high-speed data transmission and power supply. Suitable for AI vision systems and data backup.
FAKRA/Mini-FAKRASupports up to 6 GHz RF transmission, low insertion loss, ISO 20860 and USCAR compliant. Perfect for automotive AI and radar communication.
Single Pair Ethernet (SPE)Simplify cabling by transmitting data and power over a single twisted pair (PoDL). Best for smart factories and sensor networks.
Internal High-Speed Interconnect Core Technology
Inside the system,FloatingBoard-to-board connectorPlay a key role in connecting different computing modules. These connectors support the PCIe 3.0 standard and provide transfer rates of up to 8 GT/s while providing ± 0.5mm float compensation capability.
Floating plate-to-plate: Support PCIe 3.0,8 GT/s rate and ± 0.5mm compensation, operating temperature -40°C to 105°C. Suitable for embedded systems and on-board computers.
Integrated power and data transmission
The growing power requirements of modern edge AI systems have led to enhanced Power over Ethernet (PoE) and Power over Data Lines (PoDL) technologies.
PoE : Provides up to 90W of power through standard network cables while maintaining gigabit data transmission. Suitable for high-power AI cameras and edge platforms.
PoDL: Provides up to 50W power through a single twisted pair, supporting 10 Mbps to 1 Gbps data transmission. Best suited for remote sensing and monitoring nodes.
