ROTATION
LETTERS
A plug with a given rotation letter will
mate with a receptacle with the same
rotation letter. The AB angle for a
given connect­or is the same whether
it contains pins or sockets. Only the
master key/keyway rotates in the
shell, and the minor keys are fixed.
AB angles shown are viewed from the
front face of the connec­tor, a recep-
tacle is shown below. The angles for
the plug are exactly the same except
the direction of rotation is opposite of
that shown for the receptacle.
The “N” designation is not referenced in
part number, it is omitted.
