Rectangular Connectors - Headers, Male Pins

643265-4 Application Field and Working Principle

The 643265-4 connector is a two-piece surface mount board-to-board interconnector designed to provide a reliable, high-current and low-contact-resistance connection for printed circuit boards with through hole, dual in-line, or surface mount boards. This series of surface mount connectors is ideal for applications requiring extra-wide board-to-board spacing. It is also suitable for high-speed data transmission.

The 643265-4 connector features a two-piece, dual port design. The connector has two ports, one male and one female, which accommodate boards with either through hole or surface mount technology. The ports are arranged perpendicular to each other, allowing for an easier, more efficient connection of two boards. The contact points are located on the inner and outer sides of the connector, providing increased contact density compared to single-port connectors.

The connector is designed to provide an air-tight connection, which helps to reduce thermal resistance and stress on the board. Its contact resistance is also kept low, allowing for increased electrical performance and reliability. The connector also provides a high current rating, up to 5A in the connecting mode, eliminating the need for an external current limiting device. Additionally, the connector provides EMI shielding, preventing any electrical interference between connected boards.

The 643265-4 rectangular header features robust shell construction, with a split front for easy installation. It also includes a multi-finger design, which helps to provide superior contact stability. The connector also includes a rugged latch mechanism to ensure full insertion of the female port and reliable retention of the two boards.

Overall, the 643265-4 rectangular header is an ideal solution for boards requiring extra-wide board-to-board spacing, high current rating and electrical performance. Its secure and reliable connection makes it suitable for numerous industrial and commercial applications, such as medical equipment, navigation control systems, GPU cards, telecommunications, and automotive and aerospace applications.
