Rectangular Connectors - Headers, Male Pins are electronic components with multipin construction that are used for connecting printed circuit boards, board-to-board connectors, edge connectors, and cable connectors. The B3B-XH-A(LF)(SN) is a high-density rectangular connector with low profile and side-by-side mating capabilities. It is designed to provide robust electrical insulation and mechanical protection in harsh environments. The B3B-XH-A(LF)(SN) is a part of Hirose Electric’s Rectangular Connectors Series.

Application Field

The B3B-XH-A(LF)(SN) was developed specifically for the space applications, primarily satellite communication. It operates in harsh environments with its electrical insulation properties and its signal speed is twice as fast as other models (6.25 Gbps). The high-density design helps reduce total costs and the side-by-side mating of two connectors eliminates bulky distortion. Moreover, its low profile makes it suitable for limited space applications such as blade servers, PDAs, PC servers, presentation equipment, small network switches, automotive and medical equipment.

Working Principle

The B3B-XH-A(LF)(SN) connector consists of a number of male pins arranged in two rows. Two mating connectors are aligned side-by-side and secured together with screws or locking clips. The male pins on one connector couple into the female sockets on the other connector. This type of connection is secure against shock and vibration and provides a low-resistance path for electrical signals. The contacts are protected by a metal shield and the holes in the shield allow air to pass and help dissipate any heat generated by the connection.

The connector’s electrical insulation is provided by a solid shell and the dielectric material between the shells. This removes the need for additional insulators, saving on costs and weight. The contact pins are held in place with press-fit retention and the electrical contacts are plated with gold or silver to ensure reliable connection and signal integrity. The B3B-XH-A(LF)(SN) connector is rated for up to 500V and 3.9A and is available in a variety of configurations, sizes, and colors.

Conclusion

The B3B-XH-A(LF)(SN) connector is a high-density, low profile, press-fit connector with two rows of male pins. It is ideal for space applications, offering robust electrical insulation and reliable signal integrity. The side-by-side mating enables it to be used in limited space applications such as PC servers, blade servers, PDAs, etc. It also provides a low-resistance path for electrical signals, is rated for up to 500V and 3.9A, and is available in a range of sizes and colors.
