PL74-47

Coaxial Connectors (RF) serve in various fields to connect two separate signal paths while providing shielding against external interference. Of them, the PL74-47 is a standard cylindrical connector used for radio frequency (RF) applications. It has excellent shielding properties and impedance characteristics, making it a suitable connector for RF applications.

The PL74-47 connector is a robust connection method with fastening nuts that require no special tools for installation. The body is made up of a screw-type cylindrical housing which can be machined from aluminum or brass. Its internals are molded together from insulating material like Teflon. The contacts are made of either brass or stainless steel, protected with a gold-plated finish. The contacts include two nuts with taped threads for conductivity.

The applications of the PL74-47 connector include numerous applications in fixed and mobile radio communication systems. It is also used for WiFi, GPS receivers, avionics systems, satellite systems, CATV, and microwave communications. Its excellent shielding properties make it suitable for heavy-duty applications, such as those used in military operations.

The working principle of the PL74-47 connector is simple. It uses an internal center contact and rely on the two nuts for the mechanical clamping of the cable. The internal contact allows for a consistent connection even with frequent movement between the PL74-47 connectors. The connection is made by inserting the cable’s center conductor into the connector’s inner contact. The inner contact is tightened with a wrench and the two nuts, which provide the mechanical clamping of the cable. The outer contact of the connector is then screwed down, and the whole assembly is tightened until a vibration-resistant connection is achieved.

In conclusion, the PL74-47 connectors are used for various RF applications due to their excellent shielding properties and impedance characteristics. Its simple working principle and fastening nuts make it a reliable connection method for many RF applications.
