PL75-13

Coaxial Connectors (RF) are widely used in all areas of telecommunications. In particular, the PL75-13 connector is a commonly used type in many industries. It is a standard interface for various communication networks. This article will provide a detailed introduction to the application field and working principle of this connector.

Application Field

PL75-13 connectors are designed to withstand a wide variety of environmental conditions. They are used in both indoor and outdoor applications, depending on the type and need of the application. Generally, they are used to connect various telecommunication equipment, such as radios, telephones, broadband modems, and signal transfer systems. Moreover, they are widely used in network devices, such as routers, switches, hubs, and wireless access points. They are suitable for wireless audio systems, video surveillance systems, and outdoor wireless systems. PL75-13 connectors are also widely used in transmission equipment, such as multiplexers, digital cross connect systems, amplifiers, and power amplifiers.

Working Principle

The PL75-13 connector adopts a coaxial structure. It consists of a connector body, shield, center conductor, pin, and barrel. The shield is wrapped around the pin which is inserted into the connector body. The center conductor is also inserted into the barrel. The shield is then soldered to the connector body and a strain relief is added. This helps secure the connector, preventing it from being damaged or disconnected due to external forces.

When in use, the center conductor of the connector is connected to the center of the cable, while the shield is connected to the outer part of the cable. This connection prevents EMI (electromagnetic interference) from entering the coaxial cable connection. It also helps reduce signal reflection and loss. The PL75-13 connectors have a good impedance balance, making them suitable for high frequency transmission.

Conclusion

The PL75-13 connector is an important component of the communication industry. It plays an important role in connecting various communication devices and ensuring the transmission of signals. Its special structure and working principle can effectively reduce signal interference and ensure good transmission performance. Therefore, it is widely used in various fields of communication engineering.
