Hirose’s BM29 series provides robust, high-power and space-saving connections for applications in which space is limited, as in many portable and consumer devices.

The BM29 range of connectors consists of plugs and receptacles to provide a power and signal connection between a Flat Printed Circuit (FPC) and a board.

The compact design of the BM29 has a low stack height of 0.6mm, a depth of 1.5mm and a width of 3.16mm. This makes the low-profile BM29 one of the smallest hybrid FPC-to-board connectors in the world. The connector is a hybrid design which includes signal contacts rated at 0.3A and power contacts rated at 3A.

Although the dimensions are compact, performance is not compromised, and the connectors are able to offer highly reliable mechanical connection. This is due to the provision of unique two-point contacts and an effective mating length of 0.1mm.

Guide ribs are incorporated into the housing body to provide a self-alignment range of 0.3mm in the x direction and 0.24mm in the y direction. This design also gives a smoother mating operation.

The robust housing incorporates a metal guide to prevent any damage due to incorrect mating. Metal locks which increase the retention force are provided to prevent any unintended unmating due to drop impacts.
