Housing for a 4-Circuit 1.20mm Pitch Harness
The JST ACHFR-04V-H is a 4-position receptacle housing from the ACHF series, designed for crimp-terminated female blade socket contacts in a single row on 0.047" (1.20 mm) pitch.
The housing accepts female blade socket contacts (sold separately — the housing ships empty). Crimp the correct terminal onto 20–28 AWG wire, insert it into the rear cavity until the detent locks it, then mate the loaded housing with the ACHF-series plug header that carries the male pins. The 1.20 mm pitch means the mating header footprint on the PCB is compact, so confirm the header pin spacing matches before committing the layout.
