About Delta’s Customer-Driven Design
At Delta, Customer-Driven Design isn’t just a catchy slogan. It means that we make RF
connectors that help you build your products efficiently, quickly, and cost-effectively. Because
we design for your needs, nobody else can offer you such a broad line of standard connectors,
along with an ever-growing list of innovative, user-friendly design variations like those detailed
on these pages.
These featured connector technologies grew out of real-world requirements, and have saved
our customers untold hours and dollars over the years. And there are thousands of other
special connector designs we’ve produced that we don’t have space to include in this catalog.
So if you don’t see the exact connector configuration you need, please call us—we may have
already made it. If not, we’ll work with you to provide the the connectors you need, with the
best price/performance balance in the business, and with quality and delivery that will enhance
your products and production schedules.
Plating Options for Economy and Performance
(Albaloy or nickel—available for all connector series except SMA)
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. 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 listed finish, substitute
A, N, or Qin the Delta part number as below:
For silver plating: 1111-111-A111.
For nickel plating: 1111-111-N111.
For Albaloy plating: 1111-111-Q111.
Note: M39012 and M55339 QPL connectors can only be supplied with the
specified plating. SMA connectors with stainless-steel bodies are available
with gold plating or passivated finish.
