Master Key / Keyway Position
N designates normal position. Positions 1, 4, 5 and 6 of the master key/keyway
prevent cross-mating of incompatible voltages. Refer to the adjacent illustration
Insert Arrangement
determined by connector size (current carrying capa-bility) and cable configuration
to be accommodated. Refer to pages 5 & 6
Contact Type
P for pin, S for socket. MS90555 and MS90557 are supplied with socket contacts
only. MS90556 and MS90558 are supplied with pin contacts only.
Alternate Insert Rotation
used to prevent cross-mating of incompatible frequencies. Absence of a letter
in this space indicates normal (0 ) position of the insert. Refer to page 7.
