The SDL-122-G-11 is a type of rectangular connector which is classified as a header, receptacle, or female socket. As the application and working principles are important factors to consider for the successful use of any product, this article will look at both aspects of the SDL-122-G-11.

Application Field

The SDL-122-G-11 is a type of miniature, high-density connector primarily used in the telecommunications industry. It is designed primarily for RF applications, with an average insertion loss of 0.1 dB at 6 GHz, and 0.25 dB from DC-18 GHz. SDL-122-G-11 connectors are used to connect telephone lines and other telecommunications systems to telephones, cell towers, network switches and routers. They are also used in most home theatre and audio systems, and in the automotive industry for diagnostics, which is a testament to their reliability and durability.

The SDL-122-G-11 connector has a robust design with a metal shell and mateable center contact. It also has an excellent shielding performance with the addition of cable shielding or a separately preferred metal shell. It is available in a wide range of shapes and sizes, including standard and customized designs, to meet the needs of a variety of different applications.

Working Principle

The SDL-122-G-11 is a two-piece connector, with a pin-on-nut system for securely fastening the two pieces together. The nut is mounted on the inner surface of the shell and features anti-rotation grooves which prevent it from spinning in either direction. The shell has an outer wall and two inner wall components. The shell contains the actual contact pins, which are then soldered to the PCB. The two inner wall components each have a series of openings which further secure the contact pins in place.

The two inner wall components mate with the rear portion of the shell, and can be locked together by means of a bayonet mount. Both the nut and the bayonet mount work together to ensure secure connections, and also provide reinforcement against shock and vibration. Furthermore, the contact pins are designed to be resistant to corrosion and conductivity is excellent. This allows for a low return loss and excellent signal integrity at up to 18 GHz.

As one of the most reliable and durable rectangular connector solutions available, the SDL-122-G-11 is a strong all-rounder for a variety of applications. Its sturdy design ensures secure connections and its remarkable performance for RF applications make it a versatile and dependable choice.
