Coaxial Connectors (RF) are used in various applications that require transmission of high frequency, low signal voltage signals. SF1621-60009 is one such connector type that is often used for radio frequency (RF) applications such as cell phones, two-way radios, and other wireless communication devices. This article explains the application field and working principle of the SF1621-60009.

Application Field

SF1621-60009 Coaxial Connectors have one standard 5/16-32 thread and are commonly used in radio frequency (RF) applications that require high frequency and low signal voltage. High frequency signals are needed for communication devices such as cell phones, two-way radios, and other wireless systems. These connectors are also suitable for audio and video cordless devices where radio waves can carry signals within a short distance. Because of their high-frequency and low-signal voltage requirements, they are also suitable for automotive use in applications such as keyless entry systems, radio frequency identification (RFID), tire pressure monitoring systems, anti-lock brakes, and other sensors in automobiles.

Working Principle

The SF1621-60009 Coaxial Connectors feature a threaded interface and are typically used with a shielded coaxial cable. The threaded interface helps secure the connector to the cable which helps to reduce signal loss and increases the transfer of high-frequency signals. The cable is typically shielded in order to prevent electromagnetic interference and cross-talk. The connector has an inner conductor that transfers the signal from the cable to the device and an outer shield that protects the inner conductor from external electromagnetic interference and dissipates radio frequency.

The inner conductor typically consists of a solid copper core surrounded by a layer of Teflon tape or dielectric foam which helps to insulate the signal from electromagnetic interference. The outer shield is wrapped around the inner conductor and consists of an aluminum foil, copper braid, or stainless steel sheath. The outer shield works to block any external radio frequency waves that might interfere with the signal.

Conclusion

The SF1621-60009 Coaxial Connectors are suitable for a wide range of applications including RF, audio, and video cordless devices. They feature a threaded interface which helps reduce signal loss and increase the transfer of high frequency signals. The inner conductor is insulated by a layer of tape or dielectric foam while the outer shield works to block any external radio frequency waves that might interfere with the signal. These connectors are an ideal choice for cell phones, two-way radios, and other wireless communication devices.
