The BM10B(0.6)-10DP-0.4V(75) is part of the rectangular connectors array, edge type, mezzanine (board to board) family and is a versatile board-level interconnect system. Generally, these connections are highly reliable, low-profile, right-angle/surface mount configurations with multi-row transition options. This part in particular is a double row connector featuring a 0.6mm spacing, 10 DP terminal signals in each row, and a 0.4mm nominal plating thickness (gold-over-nickel).

The board-to-board mezzanine connector can be used to mate two separate boards in a vertical arrangement as opposed to the traditional parallel board interval found in traditional PC which is called the “V”. Mezzanine designs incorporate a staggered connector system that runs along the board end, with one board mounted higher than the other. This offers space savings, with smaller board separation than is possible with a traditional ‘V’ system. It also enables more mechanical strength with the mated boards and improves access for product manipulation when the boards are mounted on the same support structures.

BM10B(0.6)-10DP-0.4V(75) features an average current rating of 1.2A (max) per terminal, with an AC/DC voltage rating of up to 70V. The maximum contact resistance for a single terminal is 50 milliohms (mΩ) put the electrical lifetime at up to 500 cycles. The mechanical retention and durability features a minimum tensile retention force of 80 newtons (N). This connector is also designed for temperatures ranging from -55°C to +105°C.

The working principle of the BM10B(0.6)-10DP-0.4V(75) utilizes its spring-loaded contacts to connect two printed circuit boards (PCB) at right angles. Two rows of double-sided contact pins form the contact interface, which are placed at a distance of 0.6 mm on the mating side of the connector. The contact pins are made of beryllium copper with gold plating and have a wiping action when separated. When two connection boards are connected to each other, contact arrows move along the flat surface of the contact pins and thus make the electrical connection to the target board.

The BM10B(0.6) is heavily used in industrial telecommunications systems, consumer electronics, industrial automation, test and measurement instrumentation, audio-visual equipment, and embedded systems. Its edge-mount design meets MIL-STD- 810G requirements for shock, vibration, and temperature, making it suitable for applications where boards are subject to extreme conditions. The part is available in tape and reel packing and suitable for certain automated assembly processes.

In conclusion, the BM10B(0.6)-10DP-0.4V(75) is an ideal solution for applications in areas such as automation, test and measurement, industrial telecommunications systems, consumer electronics, audio-visual equipment and embedded systems. Its strong contact robustness, mechanical retention and durability features make this a reliable and durable part for long-term use. This part also offers space savings advantages over the traditional ‘V’ form of connection, making it ideal for applications where space is limited.
