This series is used as headers, receptacles, female sockets and provides reliable and secure connections between devices and systems. The 6.9mm series is able to meet the challenging demands of various applications, making them highly popular for various industries and markets. Let’s delve into the application field and working principle of 6.9mm series rectangular connectors

Application Field

The 6.9mm series is highly versatile and can be used in a range of applications. In the industrial sector, they are used in machine tools and electronic equipment, whilst in the automotive sector the connectors are used in fuel systems, sensors, and antennas. Additionally, the 6.9mm series are often used for applications in railways, medical systems, defense and communications, and consumer electronics. Therefore, their ability to meet the needs of various industries and applications make them well-suited for a wide range of applications.

Working Principle

The 6.9mm series of rectangular connectors operate by connecting two circuits together, allowing for power, data and signals to be passed between them. These connectors are generally designed with a huge variety of mounting styles, such as panel mount, screw-lock, and pin-engaging. The contact arrangements in 6.9mm series generally take the form of header, receptacle, or female socket. The header and receptacle, also known as male and female parts, are comprised of two halves. The header is composed of several contacts arranged in a specific pattern and is got the name header due to its shape similar to a flat head screwdriver. The receptacle, meanwhile, is composed of several female contact fittings in the matching pattern to the header and is generally made to fit the male counterpart. The female socket also works by having the contacts arranged like a header and the female contacts of a receptacle, but it consists of only one unit and has no mating parts.

Conclusion

The 6.9mm series of rectangular connectors are an essential component for many applications and markets. Their wide application in the industrial, automotive, railway, medical system, defense and communications, and consumer electronics sectors make them popular among users. Additionally, the working principle of these connectors, which is based on the male and female parts of headers and receptacles, as well as female sockets, provide reliable and secure connections. Through understanding the application field and working principle of 6.9mm series rectangular connectors, users are better able to choose the right connector for their specific requirements.
