\$\begingroup\$ Thanks, sounds about right. Sorry for the blurry pic, cropped from a larger photo. \$\endgroup\$– zencraftCommented Sep 25, 2022 at 3:56

\$\begingroup\$ What's the pin pitch? It might be Molex, might be TE/Amp. \$\endgroup\$– HearthCommented Sep 25, 2022 at 4:10

\$\begingroup\$ Actually what I really need to know is the kind of pin used inside (so I can replace it), I figure there must be a lot fewer varieties of pins than connectors \$\endgroup\$– zencraftCommented Sep 25, 2022 at 8:47

TE, Universal MATE-N-LOK II
Found using my connector identification utility
{Picture from Digikey's website}
You can buy it from Digikey. The contacts are listed at the bottom of that page.

\$\begingroup\$ Are all Mate-N-Lok connector pins interchangeable (same pin length and diameter, different only in wire gauge/material/finish/packaging)? The fools used 28AWG wire in a 14-20AWG pin, so I thought I'd get the right gauge pin. \$\endgroup\$– zencraftCommented Sep 27, 2022 at 23:47

\$\begingroup\$ No, They are not. Pins come in 3 mating diameters, and pitches vary allover the place. \$\endgroup\$ Commented Sep 29, 2022 at 17:12

\$\begingroup\$ I thought pitch was the center-to-center distance between pins, so that would be a spec of the connector housing, not the pin, no? Or is this a different pitch? Is there an easy overview guide for the world of connectors? \$\endgroup\$– zencraftCommented Sep 30, 2022 at 4:45

\$\begingroup\$ "I thought pitch was the center-to-center distance between pin". Yes, it is. "so that would be a spec of the connector housing, not the pin, no". Correct. "Or is this a different pitch?" In this family you can have different pitches for different number of contacts, even if they all use the same pin size. That's uncommon. Normally, a family of connectors all have the same pitch. \$\endgroup\$ Commented Sep 30, 2022 at 17:40
