CONNECTOR

MIL-DTL-38999

The connector of MIL-DTL-26482 Series ll Style series is a connector developed by our accumulated technology. This is of a bayonet coupling type with excellent electrical, mechanical and environmental properties, being widely used in aircraft equipment, high-tech missile communication equipment, etc. requiring high reliability. Especially, this has excellent EMI screening performing to perfectly intercept electromagnetic wave interruption, thus establish an exact signal line without external interference. This also enables wiring with a simple crimp tool during cable work, preventing inferiority during soldering, and shortening work time.
