Ouch! No, I remember the connector well, but I really don’t know where we got them from. I have a feeling it was from one of the ‘rack/enclosure’ manufacturers but I can’t remember who it was. I don’t have anything like that now.
I will have a look around myself and will relay whatever I can find.
Sorry, we can’t win them all.
I suggest hard wiring the channel to connectors.
