The Molex 431604303 is the 3-circuit single-row member of the Sabre 43160 series — a through-hole power header rated 18 A per circuit at 600 V with tin-plated brass contacts and a locking ramp fastening feature. The 0.295-inch (7.50 mm) pitch and 18 A rating position this as a mid-current board-stacking or panel-feed header; the 600 V rating handles the voltage side of most industrial AC and DC distribution rails without derating headroom concerns. Tin plating at 60.0 µin (1.52 µm) gives solid solder-wetting performance for through-hole reflow or hand-solder assembly, but the mating side is tin — not gold — so cycle life is governed by the tin-on-tin wear interface rather than a precious-metal finish. The locking ramp mechanically stakes the mated pair against vibration once seated.
The board-lock feature anchors the header to the PCB without a separate peg or clip — the housing itself locks into the board cutout. Through-hole solder legs on all contacts carry the mechanical load and the current path simultaneously. The black PA46/nylon 4/6 glass-filled insulator holds the operating temperature window from -40°C to 75°C — wide enough for unheated enclosure environments and most industrial floor or vehicle-adjacent mounting.
