Gold Plated Material Pogo Pin Connector

Gold plated material Pogo pin Connector

Why do our power aerial plug and signal aerial plug connectors always emphasize and insist on using gold-plated terminals? It is not that we use expensive materials to increase product costs, but that gold-plated materials can add stability to our connectors.

General connector products will use tin plating because tin is cheaper and has a better anti-corrosion function. At the same time, the texture of tin is also relatively soft, which is conducive to a better fit between plugs and sockets. However, because the texture of tin is relatively soft, the tin-plated surface will be worn out after multiple insertions and unplugging, which will cause the deformation of the contact end, which will not reach the designed contact force. At the same time, tin-plating will also produce work. Circumstances where the temperature does not meet the requirements.

In some ways, the working temperature of brass or bronze tin plating can reach 110°C, and the tin plating of steel can reach 190°C. For high mating cycles, gold plating is generally required. For higher operating temperatures, other coatings are needed, such as nickel plating on copper up to 340 degrees Celsius, and nickel plating on brass or bronze up to 250 degrees Celsius.

Connectors are mainly used in small-signal applications with high-reliability requirements, applications requiring small contact force, and multiple insertion and removal, so we generally use gold plating, and the corrosion resistance of gold is also very prominent. In addition to being superior to other methods in terms of corrosion resistance, gold-plated industrial connectors also greatly increase the number of insertions and removals of our products due to the wear resistance and ductility of gold. It is ensured that a high contact force can be maintained even after multiple insertions and unplugs, so as to better ensure the conductivity and the continuity of the signal. The last point is the unparalleled conductivity of gold.
