Gold Mating Interface and Termination Options
The 4-794632-4: In a field-service connector that gets cycled quarterly, that gold thickness supports decades of reliable contact. Termination is listed as press-fit or solder — the press-fit option allows solderless assembly into plated through-holes, which can reduce process steps in high-volume production. The through-hole mounting keeps the header mechanically anchored to the board.
