Gold Mating Finish and Contact Design
The 1-534998-9: The gold-on-gold interface at the mating point ensures stable contact resistance over the connector's service life, while the tin-lead solder tail provides a reliable solder joint to the PCB. The square contact shape mates with standard 0.025" square header pins common in the AMPMODU and BergStik families — no special tooling or adapter needed for the mating half.
