Product details

The locking ramp fastening holds the mated pair together without a separate latch or screw, which saves assembly time in high-volume harness builds.

The tin-on-tin contact finish is cost-effective for moderate-cycle applications — expect a few hundred mates before wear-through, which is fine for internal wiring that stays connected for the product life.

Position Variants in the GH Series

The GH series offers the same 1.25 mm pitch and 7.3 mm stack height in 7-, 8-, and 9-position headers. The 9-position BM09B-GHS-TBT(LF)(SN)(N) gives one more circuit than the 8-position BM08B-GHS-TBT and two more than the 7-position BM07B-GHS-TBT — useful when the harness needs an extra signal or ground wire without changing the connector family.

Frequently asked questions

What is the closest functional second-source to BM09B-GHS-TBT(LF)(SN)(N)?

The BM09B-GHS-TBT is the same base part number — identical 9-position, 1.25 mm pitch, SMT header. The (LF)(SN)(N) suffix indicates lead-free and tin plating; the BM09B-GHS-TBT without that suffix may be an older packaging variant. Confirm the BOM position count and mating half before substituting.
