M5 Female 3-core Board Connector

Connector Environmental performance

    Common environmental performance includes temperature resistance, moisture resistance, salt spray resistance, vibration and impact resistance.

①Heat resistance The current maximum operating temperature of connectors is 200℃ (except for a few high-temperature special connectors), and the minimum temperature is -65℃. Because the current generates heat at the contact point when the connector is working, resulting in temperature rise, it is generally believed that the operating temperature should be equal to the sum of the ambient temperature and the contact temperature rise. In some specifications, the maximum allowable rise of the connector at the rated working current is clearly specified.

② Moisture resistance The intrusion of moisture will affect the insulation performance of the connection and corrode metal parts. The constant humidity and heat test conditions are 90%~95% relative humidity (up to 98% according to product specifications), temperature +40±20℃, and the test time is at least 96 hours as specified by the product. The alternating humidity and heat test is more stringent.

③ When the salt spray resistant connector works in an environment containing moisture and salt, its metal structural parts and contact surface treatment layers may produce electrochemical corrosion, affecting the physical and electrical properties of the connector. In order to evaluate the ability of Electrical Connectors to withstand such environments, a salt spray test is specified. It is to hang the connector in a temperature-controlled test chamber and spray a sodium chloride solution of a specified concentration with compressed air to form a salt spray atmosphere. The exposure time is specified by the product specification and is at least 48 hours.
