Coaxial connectors, usually referred to as consumer RF connectors, are used to connect two coaxial cables or a coaxial cable to a device. Coaxial connectors are widely used in radio and TV broadcasting, consumer electronics, satellite communications, and other fields. Commonly used connector models include M39012/55-3028. This article will introduce the application field and working principle of the M39012/55-3028.

The M39012/55-3028 is a bi-directional connector with male and female contacts. It is composed of four pinching rings and two pins, and is a mating connector designed for general purpose applications. It is widely used in satellite communications systems and other applications that require high mated margin and reliable connections. The gold-plated contact of the M39012/55-3028 can ensure the proper mating of the connector and increase the electrical conductivity. It is also equipped with a protective sleeve, which can ensure that no dust enters the working environment and keep the connector in good contact.

The M39012/55-3028 is a precision connector. Its outer and inner conductors are precisely joined to ensure the reliability of the transmission. The inner conductor is made of copper and is tin-plated to ensure low noise transmission. The outer conductor is made of aluminum or copper, which is ribbed for better signal transmission. There is also a shielding tube inserted between the inner and outer conductors, which provides a good electromagnetic interference immunity.

The working principle of the M39012/55-3028 is relatively simple. When the male and female M39012/55-3028 connect to each other, the contact pin of the male connector will be inserted into the contact pin hole of the female connector. At this time, both sides are connected and the signal can be transmitted. The contact pinhole of the female connector has an oblique pressing surface, which can clamp the contact pin of the male connector and ensure the connection and signal transmission of the connector. The protective sleeve and contact pinhole structure of the male and female connectors are designed to achieve a good shielding effect to prevent external electromagnetic interference.

In conclusion, the M39012/55-3028 is a reliable high-end coaxial connector that is widely used in radio and TV broadcasting, consumer electronics, satellite communications, and other fields. It is designed for general purpose applications, with precision machining of its contact pins, protective sleeve and contact pinhole structure that ensures reliable and low noise signal transmission, and a reliable mated margin that provides a good shielding effect.
