Card edge connectors are designed to cryptically make an electrical connection between two separate pieces of equipment. One of the more popular styles, 530519-2 contacts feature several board lock methods and mate with Horizontal and Vertical Style D Subminiature connectors. They are ideal for computer to printer boards, link cables, or other electronic equipment applications.

The 530519-2 contact type is a staggered card edge connector. It is composed of two rows of 0.10 inch/2.5mm long stamped contacts. The design provides two point board locks to provide added security and electrical connection.

The board locks and positioning features of 530519-2 contacts are the main advantages they offer over other contact styles. The two signal rows are staggered in height, ensuring secure positioning on the mating board. The staggered rows ensure even contact pressure over each row of contacts. This ensures a positive contact when the board is inserted and properly inserted and locked into place.

Once the board is inserted, the board locks are engaged. This results in the board locks pushing the latching tabs inward. This forces the mating contact to the fixed contacts, achieving a secure electrical connection. To release the board, the latching tabs need to be pushed outward, allowing the board to be withdrawn.

The 530519-2 contact type is compatible with a selection of different connectors. It is primarily designed to mate with Horizontal and Vertical Style D Subminiature cables and boards. The contact pins are made of beryllium copper (BeCu) and plated with gold to increase electrical performance and ensure a secure connection. The contact body is constructed from high thermoplastic material, allowing the contact to stand up to the wear and tear of frequent use.

The application field for the 530519-2 contacts is mostly limited to computer and electronic equipment boards. While it can mate with Vertical and Horizontal style D Subminiature connectors, it cannot be used with D Subminiature-style 7MH and A and B wired configurations or any other type of board or cable.

In conclusion, 530519-2 contacts are a popular card edge connector style. Their staggered design allows for even contact pressure and secure positioning of the board and cable connectors. These advantages make them ideal for computer and electronic equipment applications, where secure connections are paramount and frequent connections and disconnections are common. The contacts are made of beryllium copper and plated in gold for increased electrical performance, and are durable enough to stand up to frequent wear and tear.
