12-circuit GH header with locking ramp
The BM12B-GHS-TBT(LF)(SN)(N) is the 12-circuit member of JST's GH board-to-cable/wire header line, shrouded on four walls with a locking ramp for positive retention in vibration. It carries tin-plated mating contacts rated 1 A at 50 V and mounts surface-mount with solder termination; the mated stack height is 7.3 mm.
Locking ramp and shrouding
The four-wall shroud and locking ramp protect the contacts from mis-mating and keep the pair locked under cable strain — the ramp engages audibly on mate and releases with a pull tab on the receptacle side. Pick-and-place compatible with a solder retention feature on the SMT tails, so it holds position during reflow without secondary hand-soldering.
