What this 2-position header does in a wire-to-board system
The 350428-1 is a 2-position, single-row, shrouded header from the Universal MATE-N-LOK series, designed for board-to-cable/wire applications. Its 6.35mm pitch sets the PCB footprint and the per-contact current ceiling — at typical ratings the temperature rise stays within the nylon housing limits. The locking ramp holds the mating housing in place under vibration, preventing back-out in equipment that sees shock or movement. Tin-plated mating contacts suit moderate reconnect duty — rated for fewer cycles than gold, but cost-effective for fixed installations where the connector is mated once or a few times over the product life. The through-hole solder termination anchors the header to the board with the post length (0.155" / 3.94mm) providing enough standoff for wave-solder cleaning.
