Product details

The BM09B-GHS-TBT: This is a JST GH series 9-position single-row surface-mount header, pitched at 1.25mm, designed for board-to-cable/wire applications. The shrouded 4-wall housing with a locking ramp gives a positive-lock mate that resists vibration — a common gotcha with unshrouded headers in portable or moving assemblies. The 7.3mm mated stack height sets the clearance between the PCB and the mating cable connector, so check that against your enclosure z-height budget before layout.

Board layout and termination details

The pick-and-place pad makes it assembly-line friendly. The 4-wall shroud protects the contacts during handling and guides the mating plug home.
