looking at 2-5530843-7 , 36 Position Female Connector Non Specified - Dual Edge Gold 0.100" (2.54mm) Black
is 650025-2 , Connector Keying Plug (Intercontact) For Standard Edge II Series, the correct keying part? are there any other keying parts associated with this connector?
it looks like this plug fits BETWEEN two connectors. are there any plugs that BLOCK a connector?
i would like to see all available keying parts before i make a decision.
