insert alternate positioning
To avoid cross-plugging problems in applications
requiring the use of more than one connector of the
same size and arrangement, alternate rotations are
available as indicated in the accompanying charts.
As shown in the diagram below, the front face of the pin
insert is rotated within the shell in a clockwise direction
from the normal shell key. The socket insert would be
rotated counter-clockwise the same number of degrees
in respect to the normal shell key.
