Coaxial Connectors (RF)

Coaxial connectors, commonly referred to as RF connectors, are connectors used to join coaxial cables and conductor cables together. These connectors are in common usage for signal transmission, such as television, radio, telephones, or computer networking. There are various types of coaxial connectors that range from heavy and large military applications to small types used with miniature cables.

31-203 application field and working principle

The 31-203 coaxial connector is an omnidirectional connector and is used in the 162 MHz to 174 MHz frequency range. It typically works best in consumer electronics applications, such as radios, televisions, and other audio/visual equipment. The connector is able to provide a reliable connection for the transmission of low-level signals, including analog signals. In terms of design, the connector has an insulated body made of Brass or Aluminum that is rated in IP67 protection class. Each connector also comes with Teflon insulation and has a retention force of up to 2.2 kg.

The working principle of the 31-203 coaxial connector involves direct current (DC) conduction. The contact surfaces of the connector are physically connected to each other, allowing electricity to flow freely between them. This type of connector utilizes a threaded coupling system in order for a secure connection to be achieved. In addition, the 31-203 is also capable of providing excellent shielding, thanks to the fact that there is full electrical contact between the inner and outer conductors. This is achieved by swaging the outer conductor of the connector onto the outer conductor of the cable, creating a good contact. As a result, electromagnetic signals are blocked from entering or exiting the connector.

Connectors using the 31-203 design have several advantage features that contribute to its success in consumer electronic applications. These connectors provide reliable connections in low-level signal transmission, as the contact surfaces between the conductor and the connector are hard and durable. In addition, 31-203 connectors also allow for reuse if necessary, and have a wide variety of mating connectors available. Furthermore, some versions of the 31-203 feature waterproof capabilities, which prevent the connector from deteriorating in wet conditions.

The 31-203 coaxial connector is a popular choice among consumer electronics due to its reliable connection capabilities, cheap price point, and excellent shielding mechanisms. Its ability to transmit low-level signals make it the perfect choice for a wide range of applications, such as radios, televisions, and other audio/visual equipment. The numerous advantages of the connector make it an excellent addition to any electronic system that requires reliable, low-level signal transmission.
