Circular connectors, such as the CM4840-000, are essential components of many modern electrical applications, providing a reliable interface between two or more components. Backshells and cable clamps are integral elements of any circular connector, providing a means of connecting the cable or cables to the connector body or shell. The CM4840-000 is a multi-piece backshell assembly and a set of cable clamps, designed for use in aviation, aerospace and other demanding applications.

The main body or backshell of the CM4840-000 is machined from a solid block of stainless steel, ensuring strength and reliability and providing excellent electrical and mechanical protection. The backshell is designed to provide a secure and reliable strain relief for up to four cables, positioned and held in place by either of the pre-installed cable entry sealing plugs. The strain relief ensures that the cables are fixed securely in place, whilst protecting the cable from the environment and providing a suitable interface for fitting the appropriate cable clamps.

The appropriate cable clamps, once attached to the backshell, provide the secure connection to the cables and ensure that the connector remains electrically and mechanically secure. The CM4840-000 cable clamps are designed to fit up to four cables of different sizes with a maximum outside diameter of 0.56 inches (14.36 mm). The cable clamps are manufactured from stainless steel and feature an inner lining which helps prevent chaffing and increase the life of the cable and connector.

The CM4840-000 is designed to withstand a range of environmental conditions, including temperature range of -67F to +400F (-55C to +204C), salt spray and other corrosive substances. The connector is also designed to meet military specifications and is certified to MIL-C-38999 series III standards. This means that the connector is designed to provide a secure connection with high vibration resistance, electrical performance and superior signal integrity.

In any application where the cable is subject to harsh environment or where vibration or mechanical forces may affect the electrical connection or performance, a circular connector, such as the CM4840-000, is essential. The backshell and cable clamps ensure that the cables are securely and correctly connected to the connector, providing a reliable and robust electrical link.
