Introduction of Coaxial Connector (RF) Adapters

Coaxial RF adapters are used to convert one type of coaxial cable to another, whether it's DIN Rail, Free Hanging, Panel mount, or Through Hole. These adapters are widely used in general purpose or precision test & measurement applications, allowing connections between series of connectors。

Examples include AFI, APC-2.4mm, APC-N, APC-3.5mm, BNC, DIN Coax, EFI HD, Euro, F, FMC, FME, G, H.FL, HN, MCX, MHV, MMCX, MRF 1.6/5.6, N, NEX10, NIM-CAMAC CD/N 549, Nim-Camac, OS-50, OSB, OSM, OSN, OSP, OST, OSSM, PSMP, QMA, QN, RJC-N, Reverse Polarity, SC, SMA, SMB, SMC, SMP, SMPM, SVK, TNC, TRB Twinaxial/Triaxial, TRC Twinaxial/Triaxial, TRS, U.FL, UHF, W.FL2, WSMP, 1.85 mm, 2.4 mm, 2.92 mm, 3 mm, 7 mm, 1.0/2.3, 1.6/5.6, 4.1/9.5, 4.3/10, 7/16 DIN, and 7/16.

How do They work?

Most coaxial connectors, inherited from radio technology, feature a pin (male center) known as a plug, while the mating receptacles with female contacts are referred to as jacks. In its basic form, a coaxial connector consists of a signal pin encased in a dielectric insulating material, all housed within a metal shield that forms the connector's outer casing. The center signal pin is typically a gold-plated beryllium copper contact that connects with a female contact made of similar base metal and plating. These contacts are attached to the center conductor of a coaxial cable through soldering or crimping.

The center pin is surrounded by a dielectric insulator, often made of Teflon, although other materials can be used to achieve specific performance characteristics. Finally, the connector's housing, or cable shield, is designed to connect to the coax cable's shield using solder, crimping, or clamping. The shield serves primarily to protect against external interference.
