Coaxial Connectors (RF)

Coaxial connectors are types of specialized electrical connectors which are meant for joining two pieces of coaxial cables together in order to form an electrical connection. The PL74-7 is a specific type of coaxial connector. It is a small form 7-pin connector with a total mass of only 1.1 grams. It has a ruggedized design and is capable of surviving extreme conditions.

PL74-7 Application Field

The PL74-7 is primarily used in military and aerospace applications. It is suitable for a wide range of applications such as aerospace systems, radar systems, navigation systems, telecommunication systems, and telecommunications infrastructure applications. The ruggedized design of the PL74-7 makes it an ideal choice for the harshest of environments. It is highly resistant to shock, vibration, moisture, and various fluids.

PL74-7 Working Principle

The PL74-7 is a 7-pin connector that operates at radio frequencies (RF) from DC to 6 GHz. It features excellent electrical performance including minimal insertion loss, low return loss, and excellent shielding characteristics. The performance of the PL74-7 is further enhanced by its reliable, robust construction that allows it to withstand extreme conditions.The PL74-7 consists of three main components: the outer body, which houses all the electrical contacts; the inner assembly, which contains the contacts and a ferrule, and the outer shell. The outer shell provides mechanical strength, environmental protection, and seals the connector. The ferrule helps the inner assembly stay in place and provides electrical continuity. The standard PL74-7 interface consists of seven pins that are identified by their polarity, which determine the type of signal being transmitted. The signal sent is routed to the appropriate pin and returns from the opposite pin. This is achieved through the use of an insulation displacement connector (IDC). The IDC is a small metal plunger that is secured by a plastic retainer. When the IDC is engaged, it pierces the insulation layer of the cable, which allows for the transmission of the signal through the conductor to the intended recipient.The performance of the PL74-7 can be further enhanced with the use of a MicroShield Connector. This technology provides improved shielding performance, higher frequency bandwidths, and reduced minimum insertion loss.In conclusion, the PL74-7 is an ideal choice for applications requiring extreme performance due to its rugged construction, its reliable electrical performance, and its ability to withstand harsh environments. Its small form factor makes it easy to install where space is limited, and its compatibility with MicroShield technology further enhances its performance.
