Overview

The connector is designed and manufactured in accordance with MIL-DTL-38999 K version specification. It is used in the signal and source transmission for the ground communication equipment, aviation and aerospace flied. It is small, light and easy to un-mate and fairly effective to EMI shield.

 Applications

Communication equipment, aviation, aerospace vehicle, ship, railway, airplane related equipment, industry and machinery devices, measurement and medical equipment, computer etc.

 Description

We need no tools for coupling and assembling of the connectors. It is simple to couple the connector by inserting the coupling nut of barrel into the receptacle and turning to the screw direction
