It is the board-side half of a wire-to-board interconnect — mates with the GH crimp receptacle housing (part number series GHR). The shrouded 4-wall design guides the plug into alignment and protects the contacts from bent pins during blind mating. The tin finish is matched to the receptacle terminal — tin-on-tin interface keeps contact resistance stable for the rated 30 mating cycles typical of this series. For applications requiring more cycles, the gold-plated variant (BM13B-GHS-TBT) is the same footprint. Once latched, the ramp holds the pair together against cable pull and vibration without a secondary lock. ## SMT Footprint and Board Assembly Single-row layout at 1.25mm pitch keeps the board footprint narrow — about 16.25mm across the row for 13 positions. The shrouded walls add roughly 1mm to each side, so the keep-out zone on the PCB extends beyond the pin row. Confirm the mating GH receptacle's wire gauge (28–32 AWG typical) and the crimp terminal part number (SGHR-xxT) before committing the BOM. Active lifecycle status — JST still lists this as a current catalog part.","metaTitle":"BM13B-GHS-TBT(LF)(SN)(N) JST GH Header 13 Pos 1.25mm SMT","metaDescription":"JST GH series SMT header, 13 positions, 1.25mm pitch, 1A/50V, locking ramp, active production.
