Circular Connectors - Backshells and Cable Clamps

The M85049/47W10 is a circular connector that combines the functions of Backshells and Cable Clamps into a single connector. The M85049/47W10 is a popular choice among military and aerospace applications, offering exceptional resistance to shocks, vibration, extreme environmental conditions, and corrosion. This article will review the application field and the working principle of the M85049/47W10 connector.

Application Field

The M85049/47W10 connector is used in many critical aerospace and defense applications, such as helicopters, marine vessels, land vehicles, and high-altitude aircraft. The connector offers superior performance in high vibration environments, such as with helicopters and other fast-moving vehicles, thanks to its three-ring bayonet-locking system that securely locks in the pin contacts. It is also ideal for in-flight wiring applications, as it can withstand the atmospheric pressures and extreme temperature changes of high altitudes. Due to its combination of Backshells and Cable Clamps, the M85049/47W10 also offers superior protection in extreme electromagnetic interference (EMI) or radio frequency interference (RFI) environments. It meets all the stringent requirements of military/aerospace specification M85049, including a minimized electrical notch effect for improved immunity to EMI/RFI.

Working Principle

The M85049/47W10\'s combination of Backshells and Cable Clamps allows for quick and reliable connections between cable and connector components. It relies on three bayonet-locking rings— each composed of eight contact points and a set of lugs for locking—to achieve a secure connection. It also offers superior resistance to corrosion, shocks, and vibration, thanks to its smart construction pre-lubricated contact surfaces.The M85049/47W10 is also designed to meet the most stringent military and aerospace requirements. It is compatible with a wide variety of signal and power cables, including MIL-DTL-38999-style, VG series, Amphenol ED series, and other lines. It is available in both reverse jam and screw machined cable clamp styles, and is rated for 15-amp circuits and up to 600 volts.

Conclusion

The M85049/47W10 connector is an excellent choice for military and aerospace applications, as it is designed to withstand the extreme environmental conditions and high vibration experienced in these types of applications. Its combination of Backshells and Cable Clamps ensures a secure connection, while its three bayonet-locking rings and corrosion-resistant pre-lubricated contact surfaces provide superior performance and protection.
