SFM-145-02-S-D-P Application Field and Working Principle

SFM-145-02-S-D-P is a rectangular connector style used in several applications, most commonly in radio-frequency and coaxial applications. These connectors are designed to provide a way for signals to pass from one device to another, or from a device to an antenna. These connectors come in many varieties, but most often are soldered or crimped onto the coaxial cable. This article will discuss the similarities and differences between the SFM-145-02-S-D-P and other rectangular connectors, as well as its application field and working principle.

similarities and differences between SFM-145-02-S-D-P and other rectangular connectors

SFM-145-02-S-D-P is classified as a type of rectangular connectors, alongside other popular plugs such as SMA, FME, and TNC. All these connectors incorporate the use of a pin-and-socket style, offering an insertable connecting point where device signals can be quickly and easily established. Though the way in which they are built differ slightly and the necessary cable and tools may fundamentally vary, the working principle of each type of connector remains the same.

Each connector style offers different benefits based on the particular application. SMA plugs, for example, are commonly used in lower frequency ranges, lower power operating ranges, and in higher loss applications than the SFM-145-02-S-D-P. FME plugs, with its small form factor, slimmer profile, and inventive locking mechanism, is best for locations that require greater space efficiency. TNC connectors are typically employed when low or no-loss transmission is needed, and tighter emission control is desirable.

The SFM-145-02-S-D-P is usually the connector of choice when working with high-frequency signals, high-power signals, and low-loss transmission requirements. Its construction offers a higher quality, stronger signal connection than other connectors. It is also one of the most versatile connectors, offering adaptability to a wide range of applications.

Application Field

SFM-145-02-S-D-P connectors are commonly used in RF and microwave signal transmission. Such applications include radio communications, satellite transmission, radar systems, and antenna systems. SFM-145-02-S-D-P can handle higher frequency, higher power, and low-loss transmission requirements, making it the preferred connector for these types of systems. It is also useful in many amateur radio repeater systems, paired with an SMA connector for safety reasons.

Additionally, SFM-145-02-S-D-P connectors are used in medical imaging systems, aircraft systems, factory automation systems, and in ground and space radio stations. They are also suitable for outdoor applications, as they are weather- and water-resistant and very durable.

Working Principle

The working principle of SFM-145-02-S-D-P is similar to all other rectangular connectors. It consists of two parts, a “pin” and a “socket”. The “pin” has a rounded head that fits into the “socket” to create a physical and electrical connection between two wires, cables, or devices. The pin-and-socket design provides a reliable and secure connection, ensuring that the signal is transferred properly.

The particular design of the SFM-145-02-S-D-P, however, allows for a higher power transfer than most other rectangular connectors. This is due to the increased physical contact area between the pin and socket, which is one of the primary benefits of this connector style. Additionally, the internal components of the connector to help increase its overall efficiency and minimize any signal loss.

Conclusion

SFM-145-02-S-D-P connectors are a popular choice among professionals and hobbyists in the radio transmission industry. Their superior performance, along with their durability and weather-resistant nature, makes them a great choice for a variety of applications. Thanks to their pin-and-socket design and their high power transfer capabilities, they are able to provide a reliable and secure connection between two wires, cables, or devices.
