Of note, the eLIGO 25p connector looks a bit more solid for the metal flange on the airside.
The 3PinPwr connectors look to be the same ceramic style (photo2) but the spacing between the connectors are much closer on the aLIGO design.
The third image shows what I'm planning to use for Cable strain relief.  I need to add a couple more holes and widen the height of the shroud but I think that will work well.
