Backplane Connectors - Hard Metric, Standard

5120642-3 is a backplane connector based on Hard Metric technology, which is an internationally recognized technology standard for high-speed military and aerospace applications. It is a connector in the form of a printed circuit board with two rows of conductive contacts aligned one above the other. These contacts are perforated so that they can be fastened to the printed circuit board and test points. The exact number of contacts may vary depending on the application.

The working principle of 5120642-3 applies the same principles of standard backplane connectors, with the added feature of Hard Metric technology. This standard technology uses a grooved contact with an insulated housing surrounding it. This contact is made from a durable material such as gold, nickel or silver to create a lead-free connection. The groove design ensures that both contacts can fit securely in the grooved contact area, creating a secure connection between two devices.

The key advantage of 5120642-3 is that it is an ideal choice for use in high speed applications such as airframes, air defense systems, satellites and robotics. Its contact area is smaller than conventional connectors, making it more suitable for applications requiring a reduced area. Moreover, its Hard Metric technology safeguards against signal interference. In addition, the connector can be designed in such a way that a ballast resistor or other penetrating component can be installed under the contact area.

Other significant benefits of the 5120642-3 connector include its metallic alloy construction and its high durability. The use of thick gold plating on the connector’s contacts ensures strong corrosion resistance and improved electrical resistance for increased performance. In addition, the connector is also designed for ease of installation. Its low profile allows the board to mount flush to the edge connectors. No additional mounting hardware is required, making it a cost-effective solution for high-speed applications.

In conclusion, 5120642-3 is a backplane connector that uses Hard Metric technology for high speed applications. It is constructed with a thick gold plating to resist corrosion and its low profile design enables it to mount flush against the edge connector. Furthermore, it is easy to install and incorporates a lead-free connection. This connector is an ideal choice for applications where space and speed are a constraint.
