RJ45 connector 5 big performance, you know?

Environmental performance common environmental performance including temperature resistance, moisture resistance, salt fog resistance, vibration and impact.

Temperature Resistance: the current high operating temperature of the connector is 200 ° C (except a few high-temperature special connectors) , low temperature is -65 ° C. Because the RJ45 connector work, the current in the contact of heat, resulting in temperature rise, so it is generally considered that the working temperature should be equal to the ambient temperature and contact temperature. In some specifications, the high temperature rise allowed for connectors at rated operating current is specified. 2, moisture resistance: moisture intrusion will affect the insulation performance of H connection, and rust metal parts. The conditions of constant damp heat test are relative humidity 90% ~ 95% (up to 98% according to the product specification) , temperature + 40 ± 20 ° C, the test time is less than 96 hours according to the product specification. The alternating damp-heat test is more severe. 3. Salt spray resistance: when the RJ45 connector works in the environment containing moisture and salt, its metal structure and contact surface treatment layer may produce electrochemical corrosion, which affects the physical and electrical performance of the connector. In order to evaluate the ability of electrical connectors to withstand this environment, a salt spray test is provided. The connector is suspended in a temperature-controlled test chamber and sprayed with a Compressed air solution of the specified concentration of sodium chloride to form a salt spray atmosphere for at least 48 hours as specified in the product specification. Vibration and shock: resistance to vibration and shock is an important feature of electrical connectors and is particularly important in specific applications such as aerospace, rail and road transport, it is an important index to test the robustness of mechanical structure and electrical contact reliability of electrical connectors. There are clear provisions in the relevant test methods. Peak acceleration, duration, impulse waveform, and time of electrical continuity interruption 

It performs differently when used in different environments.
