Introduction to the M85049/31-12N Backshell and Cable ClampThe M85049/31-12N is a circular connector backshell and cable clamp designed for use in harsh environments where easy access is essential. It is made of anodized aluminum alloy construction and comes with 12 standard configurations for a variety of applications. The M85049/31-12N is a compact design with a 0.04” contact gap, a patented spring clip for increased contact retention, and an environmental sealing ring for an improved dust and water protection.Application Field and Working Principle of M85049/31-12NThe M85049/31-12N circular connector backshell and cable clamp are designed for the most demanding of applications, such as military and avionics, construction, medical, and power industries. The clamp provides superior contact retention in all environments and reliably maintains critical system connections in high vibration environments. Therefore, it is an ideal choice for applications requiring a high degree of reliability and performance.The M85049/31-12N is a locking-style connector, meaning it requires no soldering or splicing to make an electrical connection. It uses an external latch mechanism to latch onto the mating cable or connection. This design is especially useful for applications with frequent cable changing, as the latching mechanism allows for easy and secure connection of the intended cable. In addition, the patented spring clip ensures an improved contact retention even in high vibration environments.The M85049/31-12N also features a standard environmental sealing ring which provides improved protection from dust and water. This makes it an ideal choice for applications that are exposed to harsh environments. The environmental sealing ring is capable of resisting a wide range of temperatures ranging from -55°C to +121°C (-67°F to 250°F). The anodized aluminum alloy construction of the connector ensures excellent corrosion and wear resistance, making it suitable for a range of challenging conditions, such as saltwater spray or extreme temperatures.Overall, the M85049/31-12N circular connector backshell and cable clamp provides an easy to use and reliable electrical connection in demanding applications. Its design ensures contact retention and environmental sealing even in extreme conditions. As such, it is an excellent choice for a wide range of applications where maximum performance and reliability are required.
