[Click the image to enlarge it]

MS3476L14 is a plug-type connector specially designed for general purposes in military applications. MS3476L14 has five products in its spec. The component part number MS3476L14 denotes MS for the basic series, 3476 for the plug type, L for the nickel plating, and 14 for the shell size.

 

The five products can be classified from the below table-

Therefore, there are five types of contact layout available in the MS3476L14 series where different types of pin sizes are also available. However, depending on the pin sizes, the current rating of the contacts also changes.

 

The current rating of the same contacts also changes depending on the environmental and hermetic class. The current rating specification can be seen in the below table-

MS3476L14  - Overview

MS3476L14 is a plug-type connector that is available in two versions - environmental and hermetic version. The current ratings and contact resistance of the connector pins are also different in those two versions.

 

The polarization or the insulator rotated inside the metal body are different according with the shell size and contact layouts. Below image can be useful to find out the polarization-
