The new BM25 series of connectors from Hirose provides a means to conduct high amounts of power in space-constrained applications.

The BM25 range consists of plugs and receptacles which provide a connection between a Flat Printed Circuit (FPC) and a board. The connector features a hybrid design which includes signal contacts rated at 0.3A and power contacts rated at 10A.

When mated, the BM25’s parallel stack is only 0.7mm high. Although the connector’s dimensions are compact, performance is not compromised: the parts are able to offer highly reliable mechanical connections. This is due to the provision of unique four-point contacts and a long effective mating length of 0.14mm for the signal contact.

Guide ribs are incorporated into the housing body, providing for a wide self-alignment range of 0.48mm in the x direction and 0.46mm in the y direction, and permitting a smoother mating operation. The robust housing also incorporates a metal guide structure to prevent any damage due to incorrect mating.

Multi-point metal locks are provided to increase retention force and to prevent any unintended unmating due to the impact of being dropped.

The integral moulding has no gaps, thus preventing solder wicking.

  • Four signal and two power contacts
