Key/Keyway Orientations
Datum is always taken from major key or keyway. In
receptacles the major keyway always remains fixed in
relation to the mounting flange. For the B,C,E and F
orientations, the three bayonet locations and associated
minor keyways are rotated complete, in accordance with
the table below.
N.B. - The accompanying diagram shows a
receptacle shell, with keyways. Corresponding key
orientations for a mating plug shell are therefore
always clockwise.
