The Molex 34690-0122 is a STAC64 vertical header with 12 circuits and a brown polarization key — the color coding prevents mismating in multi-connector harnesses, a common source of field rework. As a vertical header, it stands perpendicular to the PCB, saving board-edge real estate and allowing direct wire-to-board connection in tight enclosures. The brown polarization key aligns with the matching STAC64 receptacle, ensuring correct orientation before the contacts engage.
ROHS3 compliant, meeting current environmental requirements for lead-free and restricted substances.
