5.2  Polarization (see figure 1).

a.    Each insert arrangement is shown in the "normal position" in the shell.

b.    In the normal position (N) the indexing radius coincides with the CL of the master key or keyway of the shell.

c.    For alternate polarization positions 1, 2, 3, 4, and 5, the socket insert is rotated clockwise relative to the centerline of the master key or keyway of the shell.

d.    For alternate polarization positions 1, 2, 3, 4, and 5, the pin insert is rotated counter- clockwise relative to the centerline of the master key or keyway of the shell.

e.    For alternate polarization positions 6, 7, 8, 9, and Y, the insert is in normal and the minor keys or keyways are relocated as indicated on figure 1 with reference to the master key or keyway.

f.    Four keys or keyways (maximum material condition (MMC)) and insert shall be located within

.004 either side of true position (TP) relative to master key or keyway (MMC) and shell outside diameter (OD) or inside diameter (ID) (MMC).

g.    Alternate insert positions 1, 2, 3, 4, and 5 are for intermateability use only.  NOT RECOMMENDED FOR NEW DESIGN.

5.3  Contacts.  Solder contacts shall be in accordance with MIL-DTL-83723 or MIL-DTL-26500.  Crimp contacts shall be specified table I or table II.
