This contact mates with the matching pin contacts in any AMPLIMITE HDP-20 D-sub connector housing — the same series used across TE's DB-9, DB-15, DB-25, and HD-44 shells. The 30.0µin gold thickness is the heavy-duty plating grade, specified for applications requiring repeated mating cycles or operation in corrosive environments where tin or flash gold would wear through.
Why the gold thickness matters for your build
At 30.0µin (0.76µm), the gold on this contact is well above the 15–20 µin flash typical of commodity signal contacts. For a D-sub on a panel that gets reconnected during field service or test, this contact holds its rated current longer than a tin-plated equivalent. The phosphor bronze spring beam provides consistent normal force across those cycles.
