The locking ramp fastens securely with the mating GH receptacle housing — the audible latch confirms full engagement, critical for assemblies subject to vibration or cable strain.
Pitch, circuit count, and board footprint
At 1.25mm pitch, the 15-position layout demands a tight footprint — the 0.049" spacing sets the trace routing density on the PCB. The mated stack height of 7.3mm is fixed; the header's insulation height of 4.05mm leaves clearance for the wire exit angle from the mating receptacle. Compared to the 14-position BM14B-GHS-TBT(LF)(SN)(N) or the 13-position BM13B-GHS-TBT, this 15-position variant adds one or two additional signal lines within the same connector length increment — useful when a BOM requires an extra ground or sense line without switching to a dual-row layout.
Mates with JST GH series crimp-style receptacle housings (e.g., part number family GHR-xxV-S). The UL94 V-0 nylon 9T housing withstands the reflow profile without deformation.
