The 2-2834465-4: This is a 24-position header from TE's Mini Dynamic series, with tin-plated contacts and an X-key polarization to prevent mis-mating. It's designed for wire-to-board applications where the board header needs to stay put and the harness plug cycles on and off — think control boxes, small appliances, and automotive interior modules where the connector sees occasional service access. The header is supplied on Tape & Reel, so it's set up for automated pick-and-place on a standard SMT line. That saves a manual insertion step if your volume justifies the setup.
