Connector Plating Options

Silver plating has long been standard on RF connectors with brass bodies, but its high cost and low corrosion resistance make it less than ideal in most applications. Silver plating is still required on many M39012 QPL connectors and
M55339 QPL adapters.
Nickel plating is less expensive and more durable than silver, and is standard on many of our connectors. However, in
some applications, nickel plating can introduce unwanted intermodulation distortion, particularly on large size connectors.
For these applications, we offer optional Albaloy plating, a tin / zinc / copper composite with a bright white finish, the corrosion resistance of nickel, and the low intermodulation distortion of silver plating. Albaloy plating has the same composition as, and is fully compatible with, other commercial platings designated Sucoplate, IP-23, White Bronze,
and Tri-Alloy.
To order a Delta connector with plating other than the finish shown as standard in our catalog,
substitute G, A, N, K, or Q in the Delta part number as below:
• For Gold plating: 1111-111-G111.
• For Silver plating: 1111-111-A111.
• For Passivated finish (Stainless-steel body connectors only: 1111-111-K111.
• For Nickel plating: 1111-111-N111.
• For Albaloy plating: 1111-111-Q111.
Note: M39012 and M55339 QPL connectors can only be supplied with the plating specified in the slash sheet.
