Pitch looks to be around 0.156", blade width 0.110".
Does it have any markings on it?
I have looked through what we have and have not had luck locating a match.
Yes, it has “111R 42”, you can kind of see it at the bottom of the second Pic.
I have found this housing, and it’s mate on a motorcycle parts site; NAMZ NH-ML-6AL, referred to as ML110 series. I have seen this connector on Cars, Motorcycles (for decades), and currently E-Bikes. Which is my current interest in finding it’s manufacturer.
I suspect that this is a Chinese knock-off of somebody’s connector. But, who’s. . .
That looks like the 2.8mm connector like these here. Unfortunately, I don’t see this connector in our system.
