CRANE-99808
Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a protective backshell for electrical cables that protects against electromagnetic interference (EMI). EMI occurs when two electrical signals cross paths and one signal acts as an antenna and draws in the signal of another source causing attenuation or loss of a signal. A backshell in an enclosure protects the ends of the two separate cables from EMI. The invention consists of an aluminum shell that protects cables. The shell contains an EMI protective gasket.

This technology is used in cables that are highly susceptible to EMI. It solves the problem of cables being exposed to EMI which causes them to distort results or function in electrical equipment. In the commercial sector, the technology can be potentially beneficial in the medical field with large scale electrical equipment used in hospitals.

Advantages:
- Exceeds Mil Spec 461 for shielding EMI
- Effectively shields 95%+
-The only EMI backshield approved for EA-18G aircraft platform and used in satellite communication and radar

Potential Applications:
- Medical Equipment
- Video and Infrared
- Radar
- Antenna
- Aviation
