JST BM04B-GHS-TBT

Four-position GH 1.25 mm top-entry SMT header. Manufacturer drawing, pages 2–3.

The top-entry PCB header is 8.25 mm wide including retention tabs, with 3.75 mm span between the outer signal pins. It mates with GHR-04V-S. The footprint has four electrical pads and two mechanical solder tabs. STEP and footprint derive from KiCad libraries under their separate license; this is not manufacturer CAD.

GH contacts accept AWG30–26 with 0.76–1.00 mm insulation diameter. The family catalog rating is 1 A with AWG26, 50 V and −40 to105°C including current heating; verify the actual harness conductor and crimp process. SSHL-003 contacts are not a substitute. The pin numbers describe contact positions, not project signals. Check polarity from the mating face before assembly.

Native parser and rendered geometry checks are design evidence, not physical fit, pull-test or repeated-mating qualification.
