Coaxial Connectors (RF): BJ157F-2C Application Field and Working Principle

A coaxial connector, also known as an RF connector, is an electronic device that connects two pieces of electrical conductors and provides electromagnetic interference shielding. This type of connector is widely used in telecommunication networks, as well as for many audio applications. As one of the most commonly used RF connector, the BJ157F-2C is designed to work in certain types of communication networks and electronic appliances.

Application Field

The BJ157F-2C is most commonly used for telecom frequency bands from 0.3 MHz to 3 GHz. It is suitable for both indoor and outdoor environments and is budget-friendly, being available at cheaper prices than other RF connectors. Additionally, its high frequency performance and low VSWR make it ideal for antenna signals, automotive communications, Wi-Fi, and Bluetooth applications.

Design and Working Principle

The BJ157F-2C is a precision-made square socket connector with a transmission speed of up to 4gbit/s. It has a center contact that is held in place by a ceramic body and a steel shell, and a threaded contact that locks into the ceramic body. It has two outer shields that absorb most of the electromagnetic interference. The two outer shields are connected to the center contact in order to provide a low-impedance path for the current to travel in order to reduce signal loss.The BJ157F-2C has a snap-lock design that provides a secure and reliable connection that is resistant to vibration and provides a higher retention force for maximum security. Its design prevents potential disconnections in unfavorable conditions such as vibration, temperature changes, shock, and climatic effects. The BJ157F-2C is shielded with epoxy and gold-plated contacts, which makes it more durable and immune to interference. This makes sure that the connector has maximum signal integrity and reliability.

Additional Features:

The BJ157F-2C also has a keyed plug which helps to prevent wrong connections. It has a maximum temperature rating of 105 ºC, has a water seal rating of IP67 and is also RoHS compliant.In conclusion, the BJ157F-2C is a reliable and cost-effective high-frequency connector suitable for a wide variety of applications including telecommunications, broadcast, military and automotive. It guarantees maximum signal integrity and noise protection, making it suitable for audio and video applications. Due to its small size and modern design, the BJ157F-2C is perfectly suited for use in tight spaces and in harsh conditions.
