Additional Connector Features
Body Materials
Coaxial connector manufacturers produce various
body materials to suit different needs and performance
requirements. Standard materials include brass, stainless
steel, beryllium copper, and others.
Generally, designers should choose the material based on
the specific application's needs. For instance, stainless steel
offers greater durability than brass, making it suitable for
applications requiring many mating cycles.
Plating Options
Manufacturers also provide various plating options for coaxial
connectors. Standard plating materials include gold, nickel,
white bronze alloy, silver, and tin. Manufacturers commonly
use gold and nickel, with white bronze also frequently used.
Insulation
Manufacturers most commonly use PTFE
(Polytetrafluoroethylene) as connector insulators. However,
some high-performance, higher-frequency connectors
employ a different design. These connectors use Ultem
beads featuring air-articulated holes, which can enhance
performance at higher frequencies.
Design Custom Solutions
When designing a custom coaxial connector, you must
consider your application's specific requirements. The
materials you choose for the body, plating, and insulator
can significantly impact the connector's performance and
durability. By understanding the properties of different
materials, you can make informed decisions to ensure your
coaxial connections meet your needs.
