Board layout and wire routing with the MTA-100 right-angle header
The 2-644488-3 is a 3-position, single-row header from the MTA-100 series, designed for board-to-cable/wire interconnects. The 4-wall shroud protects the pins during handling and guides the receptacle into alignment. A friction lock on the shroud holds the mated pair without a separate latch or hardware, providing vibration resistance for the wire-to-board joint in general-purpose equipment.
Contact plating and current handling for moderate-duty cycles
Both the mating contact finish and the solder post are tin-plated. Tin-on-tin interfaces are cost-effective for applications with limited mating cycles — typical for a header that mates once during assembly and stays connected. The current rating varies by wire gauge, so the limiting factor is the attached wire, not the header pin itself.
