Product details

Right-angle SMT header for 1.2mm pitch wire-to-board

The BM04B-ACHSS-A-GAN-TF is a 4-position, single-row header from JST's ACH series, pitched at 0.047" (1.20mm) and terminated via surface-mount solder in a right-angle orientation.

Pitch, position count, and locking for BOM fit

At 1.20mm pitch and 4 positions, this header occupies a narrow board footprint — roughly 4.8mm along the mating axis plus the right-angle tail overhang. The 3-wall shrouding guides the receptacle into alignment before the detent lock engages. If your BOM calls for 4 positions, this is the correct member; the 5-position variant will not mate with a 4-position receptacle.

Sourcing and compliance for the build line

RoHS compliant and rated UL94 V-0 for the housing material.
