1. In the normal insert clocking position (position N),
the insert centerline coincides with the centerline of the
master keyway (key) of the shell: L = 0°.
2. In the alternate clocking positions (W, X, Y and Z),
the pin insert (viewing from mating side) is rotated
clockwise relative to the centerline of the master
keyway (key) of the shell.
3. The socket insert is rotated counter-clockwise.
4. Plugs have keyways; receptacles have keys.
Note: Be careful with alternate positions. See table below for
position availability on layouts of interest.
