The JST ACHFR-06V-H is a 6-position single-row receptacle housing from the ACHF series, designed for compact wire-to-board interconnects. It uses a 1.20mm pitch, which keeps the housing narrow for dense harness routing — common in automotive interior modules, small appliance control boards, and industrial sensor wiring where board space is tight. The housing is gray and carries a detent lock that provides a positive tactile click when mated, holding the pair together under vibration without a secondary latch.
This is a receptacle housing only — contacts are not included. The housing accepts female blade socket crimp terminals after crimping onto the wire. The free-hanging (in-line) mounting means it's intended as a flying connector on a wire harness, not a board-mounted header; it mates with the corresponding ACHF series pin header (soldered to the PCB).
