What factors affect the performance of RJ45 connectors? Here are some factors that affect RJ45 connectors, which you may find useful to know: insulating materials, temperature, humidity, contamination, test voltage, and the duration for which the test voltage is applied continuously. The following are the detailed key points: Insulation material for Rj45 connectors. It is very important to choose the right insulation material when designing Rj45 connectors, as this often determines whether the insulation resistance of the resulting product will be stable and within acceptable levels. Previously, some factories used materials such as acetal glass fiber plastic and reinforced nylon to manufacture insulators; these materials contain polar groups and are highly hygroscopic. Their insulation properties meet the requirements for products at normal temperatures, but they fail to meet such requirements in high-temperature and humid conditions. Subsequently, the special engineering plastic PES (polyphenylene ether sulfone) was used; after undergoing tests at 200°C for 1000 hours as well as 240 hours in humid conditions, the insulation resistance showed only minor changes, remaining above 105 MΩ with no abnormal fluctuations. Temperature of Rj45 connectors: High temperatures can damage the insulating material, leading to a decrease in insulation resistance and voltage tolerance. As for the metal casing, high temperatures can cause the contacts to lose their elasticity, accelerating oxidation and leading to deterioration of the coating. For products in Series 2 of environment-resistant quick-disconnect electrical connectors manufactured in accordance with GJB598, the insulation resistance is required to be no less than 5000 MΩ at 25°C, while at the higher temperature of 200°C, it should still be no less than 500 MΩ. Rj45 connector humidity: Humid environments cause water vapor to be absorbed and spread on the surface of the insulators, which can easily reduce the insulation resistance to below the MΩ range. Prolonged exposure to high-temperature environments can cause physical deformation, decomposition, and emission of products from insulators, leading to outgassing effects, electrolytic corrosion, and cracks.
