Black Hole
May contain traces of nut
I am hoping somebody can tell me what make of connector this is. As a general description it is a 0.1" pitch single row cable-to-PCB interconnect system, and this is the crimp housing for the cable end (the PCB end is a row of pins in a plastic box housing, probably 0.025" square pins - most are).
There are lots of types of these, but the distinguishing feature is the polarising lumps which are also latches (not very clear in the photo, but I have enhanced the contrast). These click into similar slots on the pin housing, separate for 3-way upwards but as a single wide slot in the 2-way housing.
I have done a Google, and looked at loads of illustrations, so don't bother unless you have time on your hands. The hope is that somebody has seen one before and knows what it is.
