Coding - polarization

To avoid cross-plugging problems in applications requiring the use of more than one MIL-DTL-38999 II

connector of the same size, alternate key-rotations are available as indicated in the chart below. As shown

in the accompanying diagram, the major key rotates clockwise from the secondary ones.

In the reference system, the polarization is shown by the letters A, B, C or D.
