Background of Coaxial Connectors

A coaxial connector is an electrical connector, commonly referred to as an RF (radio frequency) connector. It is a cylindrical device used to connect two electrical circuits together. Coaxial connectors are most commonly found in the consumer electronics and broadcast industries, where RF signals are used for various purposes, such as connecting a TV and a satellite dish. However, coaxial connectors are also used in automotive, communications, computer, and other industries.

BJ74C-201 Coaxial Connector

BJ74C-201 is a type of coaxial connector manufactured by Hirose Electric. It is a 75 ohm version of Hirose\'s popular RJ-45 style RJF series of connectors. The BJ74C-201 is a miniature type connector that is particularly suitable for board to board applications. It is a 3G/HDTV compliant, four-way connector that is compatible with Hirose\'s own U.FL and FH connectors.

Application Field

The BJ74C-201 is best suited for high performance applications and is typically used in applications in which high-speed digital transmission or low noise signal transmission is required. Such applications may include CATV receivers and transmitters, broadcast video monitoring, camera modules, television antennas, and video and audio cabling. It is particularly popular among manufacturers of studio and broadcast equipment, as well as in the professional audio/visual industry.

Working Principle

The BJ74C-201 adaptor connector works by establishing an electrical connection between two circuits. It does this by containing four contacts which form a pin-and-socket set. The contacts are crimped onto two separate cable terminations and then mated together. This creates a hermetic seal which helps protect the contacts from moisture and corrosion. It also creates a secure electrical connection which significantly reduces interference and ensures the highest possible data transfer rates.

Conclusion

The BJ74C-201 coaxial connector is an ideal choice for applications that require reliable, low-noise, and high-speed transmission of digital signals. Its small size and robust design enable it to withstand harsh environmental conditions and gives it an edge over many other connectors of its kind. With its broad usage across many industries, the BJ74C-201 remains a popular choice for many applications.
