MD15

Circular Cable Assemblies

MD15 is an internationally accepted standard for circular cable assembly, specifying both physical and electrical parameters. This versatile connector family offers a broad range of connector types, sizes, and mounting options, making it well-suited for a wide range of industrial and commercial applications.

Application Field

The MD15 family of circular connectors is well-suited for a wide range of applications, including, but not limited to:

• Telecommunications
• Medical equipment
• Industrial control systems
• Aviation
• Marine systems
• Military applications

The MD15 family can also be used for high-density applications, both on the board level and cabling level, such as:

• Dense wiring assemblies
• High-performance, high-speed systems
• High power applications
• High voltage applications
• High current applications

MD15 connectors are also suitable for applications in harsh environment, featuring resistance to environmental stresses, such as vibration, Arctic cold, tropical heat, and corrosive atmosphere.

Working Principle

The MD15 is a circular cable assembly that utilizes a single open design for both male and female connectors. Each of the different connector sizes of the MD15 family has the same fundamental design, although the number of contacts may vary depending on the requirement.

The main elements of the MD15 common design are:

• Shell: The shell is the external body of the connector that houses the contact pin and sleeve and is designed to provide strain relief and environmental protection.
• Pin: The pin is the male contact of the connector that is inserted into the mating female contact sleeve.
• Sleeve: The sleeve is the female contact of the connector that accepts the male pin and forms the connection. The sleeve can be either open or closed, depending on the application.
• Retainer clip: The retainer clip holds the cable in place and provides strain relief.

The MD15 connectors are beater-resistant and have keyed mating surfaces to ensure proper coupling alignment. The pins can also be inserted in different levels to ensure proper mating with the socket.

The MD15 connectors provide a secure, reliable connection that is suitable for high temperature and harsh environment applications. The connectors are robust and can withstand a wide range of temperatures, ranging from -10 to 70 degrees Celsius.

Conclusion

The MD15 family of circular connectors offers a versatile and reliable connection solution for a wide range of applications, from telecommunications to industrial systems to aerospace. The connectors provide good electrical contact with a simple but effective design, and are capable of withstanding a wide range of temperatures and harsh environments. As such, the MD15 connectors are an excellent choice for any application requiring a reliable, robust, and cost-effective connection solution.
