Connector Annoyances: Micro-Fit Genders
Connectors can be very annoying.Â 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.Â 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).Â I was investigating building a simple PCB to test the cable, and therefore needed a PCB mount receptacle.
That part doesn’t exist.Â All the standard Micro-Fit PCB headers are plugs.Â 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.Â And you can choose solder cup, crimp, or (for some sizes) IDC ribbon cable; Micro-Fit is only crimp.
