Modern network devices have put forward higher requirements for data transmission rate and power transmission capacity. As a key interface, the rj45 modular jack must meet both of these demands simultaneously. Taking the products of Shenzhen Suoling Electronic Technology Co., Ltd. as an example, its RJ45 connector that supports PoE function adopts a specially designed 8P8C contact structure. The contact material uses phosphor bronze with a gold-plated surface (1.5μm thick), and the contact resistance is controlled below 20mΩ. It can support a maximum power transmission of 90W under the IEEE 802.3bt standard. At the same time, maintain a data transmission rate of 10Gbps. In terms of temperature adaptability, the performance of these connectors fluctuates by less than 2% within the ambient temperature range of -40℃ to 85℃, ensuring that the PoE power supply stability in industrial environments reaches over 99.7%.
Electrical performance design is the core to ensure the stable operation of dual functions. The rj45 modular jack product of Soling integrates an EMI metal shielding housing and a special grounding design, suppressing electromagnetic interference above 60dB and keeping the signal transmission bit error rate at the 10^-12 level. In terms of structural design, the insulator is made of high-temperature resistant PA9T material (UL94V-0 grade), supporting a maximum withstand voltage of 250V and an insulation resistance value exceeding 500MΩ. Actual test data shows that under the full-load 90W power transmission state, the temperature rise of the connector is controlled within 15℃, fully meeting the heat dissipation requirements of PoE++ equipment.
Reliability verification data shows that after 1,000 insertion and extraction cycle tests, the contact resistance change rate still remains within 105% of the initial value. In a smart factory deployment case in 2023, over 5,000 PoE monitoring devices equipped with Solin RJ45 connectors operated continuously for 10,000 hours without failure, and the data packet loss rate for transmitting 4K video streams was only 0.001%. These connectors have also been certified by UL and IATF16949. After 1000 hours of testing in an 85% humidity environment, they still maintain an insulation resistance of over 100MΩ.
In terms of manufacturing process, Soling ensures that the contact spacing accuracy reaches ±0.05mm through precision stamping dies and uses automated CCD inspection to achieve 100% full product inspection. The delivery cycle of its PoE rj45 modular jack products can be shortened to 9-12 days, with an urgent order fulfillment rate as high as 91%, and it offers a 48-hour rapid prototyping service. These technical features enable the single-port RJ45 connector to stably provide 71.3W of effective power to PD devices while transmitting 10Gbps of data, with a power transmission efficiency of 94.5%, and perfect compatibility with multiple protocol standards such as 802.3at/af/bt.
