Duplex CSA are global suppliers of standard and customised RF connectors and interconnect solutions, cable assemblies, and shielding products. We provide the electronics industry with high quality interconnections at competitive prices, while also ensuring our customers receive a flexible, personalised service that includes an immediate quotation and next day delivery. This means our customers' short and long term requirements are met and their production continues to run without downtime. This is how Duplex CSA has been able to quickly expand to become one of the world's leading suppliers of coaxial connectors, cable assemblies and shielding products.

Since we were established in 1992, the company has continually grown its product portfolio to serve a wide range of applications in the electronics, telecommunications, cable/satellite, and wireless systems industries. Duplex CSA is able to draw upon extensive worldwide resources to meet our customers' needs on a local, regional and global level.

Whether you have a special plating requirement, or need an unusual in-line adaptor or odd cable size, Duplex CSA has the co-axial connection to suit every customer. We are also able to offer a wide range of in-series and between-series adaptors that allow any two types of connectors to be coupled together. Connectors and cables can easily be mixed and matched extremely quickly and in large quantities. So if you're looking for the most extensive range of cable connections, make sure you head straight to Duplex CSA. We're always happy to receive your enquiries, so just give us a call.

Below are just some of the products we have to offer; if you would like to find out more, please head directly to the Duplex CSA website.

Standard Connectors

Duplex CSA offers a comprehensive range of standard coaxial connector types, including;
BNC, mini BNC, UHF, mini UHF, TNC, F-series, N Series SMA, SMB, RCA, Twin-ax, IEC,
Phono series, and many more.

All of our connectors are available in male/female variants, straight or right angle versions, with various mountings to suit panel cables or PCBs. All types can be provided in a number of platings, including nickel, tin, gold and silver. Whatever connector you need, it's highly likely we've
got it in our standard range. Just give us a call or send us an email with your requirements!

Custom Connectors

There are not many other companies that have spent so much time, effort and money in investigating unusual design requirements. In fact, one of the most important aspects of our growth has been our ability to manufacture custom connectors within weeks rather than months, and in quantities that most of our competitors would consider a non-viable proposition.

Just send us your sketches, no matter how simple or complex, and we'll provide a prototype sample within 14-21 days. If you're happy, we’ll get the ball rolling and have your custom connectors ready in just six weeks.

We can cater for even the most unusual plating requirements, mounting brackets, and dielectric arrangements.

Metalwork Assemblies

Duplex CSA has made significant investments into our metalwork facilities. From the simplest bracket to the most complex tuner can, we are able to manufacture virtually any metalwork assembly to the most exacting design specifications. With our very own in-house design team, Duplex CSA is able to generate detailed designs from the most basic drawings. We have considerable experience of swaging in our precision connectors to withstand high torques, and our low-cost progression tools allow us to offer a fast turnaround and extremely competitive prices.

Metalwork prototypes can be supplied within days rather than months.

Cable Assemblies

Duplex CSA is the leading European manufacturer of fly lead assemblies, and using high quality, low-cost components, we are able to offer exceptional products at the most competitive prices anywhere in the market. We stock all relevant piece parts rather than finished products, meaning connectors and cables can be mixed and matched in large quantities, extremely quickly.

Duplex CSA is currently producing tens of thousands of fly lead assemblies every week, so our customers can benefit from next day delivery. Send us an email with your requirements and we'll get
back to you with a highly competitive quote.

DPX Range

Our DPX range of connectors are available in F series female, TV male and female variants, and can be supplied in all mounting types, including PCB mount and Bulkhead mount. These connectors have been designed to offer exceptional return loss performance at a very low-cost. If you would like to find out more about our DPX range of connectors, just give our sales team a call.

Miniature Connectors

Over the years, Duplex CSA has built strong, lasting relationships with a number of suppliers in the electronics industry. Through our strategic partner, I-PEX, we are able to offer a broad range of top-quality miniature connectors. They include: small gauge coaxial connectors, micro miniature RF coaxial connectors, FFC/FPC connectors, and docking connectors.
