The BM02B-ACHSS-GAN-TF is a 2-position, single-row header from JST's ACH series, pitched at 1.20 mm and rated 2 A per contact at 50 V. The shrouded 3-wall housing guides the mating plug and protects the male blade contacts from bent pins during blind-mate assembly. A detent lock holds the mated pair without a secondary latch, and the solder retention feature anchors the part during reflow.
Pitch, current, and contact finish — what drives the fit
At 1.20 mm pitch and 2 A, this header is built for signal-level interconnects — not power delivery. The gold-plated mating contacts support repeated mating cycles better than tin, making it a reasonable choice for field-serviceable or test-point connections where the cable is disconnected occasionally. The base product number BM02B-AC identifies the family; the full order code BM02B-ACHSS-GAN-TF specifies the gold-plated, SMT right-angle variant with tape-and-reel packaging.
