A miniature board-to-Flexible Printed Circuit (FPC) connector has been developed by Hirose which is designed for battery pack connections in mobile devices. With a space-saving design that includes a 0.35mm pitch, stacking height of only 0.6mm, and depth of 1.5mm, the low-profile BM29 Series is the smallest hybrid board-to-FPC connector on the market. 

The smaller and narrower connector offers design flexibility and enables the miniaturisation of portables devices in a wide range of industries.

The hybrid BM29 Series connector is rated up to 3A per pin for power contacts and 0.3A per pin for signal contacts. Currently available in a two-position version, with six-position and 10-position models under development, the BM29 Series meets the power and signal transition needs for a variety of handheld consumer, inventory control, IoT, medical, point of sale, and other wireless equipment.

A highly reliable two-point contact design combined with a robust metal lock provides a mating force that is resistant to intense vibration and drop impact. This positive locking mechanism ensures secure mating with a clear tactile click. The BM29 Series connector also utilises a metal guide that prevents housing damage due to incorrect mating. The metal guide design ensures that if the header and the receptacle should be mated incorrectly, the metal hold-downs dissipate the force and prevents housing damage.

Offering simple and easy mating operation, the BM29 Series utilises guide ribs that provide self-alignment up to 0.3mm in the X direction and 0.24mm in the Y direction.

"Our compact BM29 Series hybrid board-to-FPC connector features a sleek design that minimises the occupied mounting area in comparison with comparable connectors on the market," said Rick van Weezel, Vice-President of Sales and Marketing for Hirose Electric USA. "Designed for mobile device connectivity, the BM29 Series connector combines miniaturisation with ruggedness to meet our customers’ next-gen designs."

This space saving connector is suitable for vacuum pick and place equipment.

The BM29 Series connector has a rated voltage of 30VAC/DC, power contact resistance of 30mΩ maximum, signal contact resistance of 100mΩ maximum, insulation resistance of 1000MΩ minimum, and an operating temperature of -40 to 85°C.
