Connector Annoyances: Micro-Fit Genders

Connectors can be very annoying.  Right now, I’m annoyed by Molex’s Micro-Fit 3.0mm connector family.

Here’s the scenario: some motors we use come with the feedback cable wired with a Micro-Fit receptacle.  We custom build a cable with a sub-D connector at one end and a Micro-Fit plug at the other (which connects to the feedback cable).  I was investigating building a simple PCB to test the cable, and therefore needed a PCB mount receptacle.

That part doesn’t exist.  All the standard Micro-Fit PCB headers are plugs.  You can get Micro-Fit PCB receptacle headers if you use the Micro-Fit BMI (Blind Mate) series, but according to Molex, BMI parts only mate to other BMI parts.

That’s another reason I like sub-D connectors: they’re available from multiple sources, in all kinds of variants.  And you can choose solder cup, crimp, or (for some sizes) IDC ribbon cable; Micro-Fit is only crimp.

same problem for me!
or have you found a solution in the meantime?
