BACKSHELL TYPE Amphenol Backshells are available in several different types, designed for optimum performance in the application or environment it will be used in. For example, in ground and naval applications, the robustness and environmental sealing may be more important, weight may be the prime consideration for Space and Aerospace applications. The following overview explains the various families of Amphenol Backshells with its applications. Some families of backshells shown here can be used without any additional protection. Some other types of backshells shown are generally used with heat...

BACKSHELL TYPE Band Lock Adapter Pre-Shield Adapter A high quality band will do the job with this backshell. Tempered bands are tightened over the shields, which are pulled over the banding area using a special assembly tool. Suitable over cover by heat shrink boot or some other method as chosen by the designer could be used. Both crimp ring and banded terminations give a low DC resistance. This adapter comes with a pre-cut braid that is fitted to the adapter for easy assembly. The braid overlaps with the cable braid. Effective shielding takes place due to the 360° contact of the braid. Designed...

ANGLES/PROFILES & COUPLING STYLES Angles/Profiles Amphenol Backshells are available in three different angular profiles: straight, 90 degree and 45 degree. These profiles will meet most of the cable routing required in the interconnect market. We can also make additional profiles if required. Please go to the web link http://www.backshellworld.com/customdesign.asp to contact Amphenol about your specific backshell needs. Straight Backshells Available in different lengths and cable entry diameters for most applications. Different cable and braid terminating systems are also available as shown in...
