I've been trying to identify this terminal all weekend and it's driving me bananas. I've searched so much that Google's asked me to verify my humanity and I'm not sure any more myself. I'm having dreams about it now.
I've been able to find it on one single site, which is this:
https://connectorexperts.com/i-31645543-term498.html?ref=category:1458515Mine is the same exactly on all of the surfaces, although mine doesn't appear to have the outer edge M and instead says M then further towards the edge SEC or SE8, the final character is illegible.
It has what would seem to me like an easily identifiable mark W/M and also that strange cog-shaped c or o logo, but I haven't been able to find it on Mouser, Digikey, Google, a few other sites but I've done deep dives on the first 2. This has so far netted me this similarity but not exactly what I'm looking for:
https://www.mouser.com/ProductDetail/TE-Connectivity-AMP/183025-1?qs=UMrTGIqlm7n5fwhEa5Ai7Q%3D%3DIt's so similar in fact that it's only missing a tab and it's shorter (16.5mm compared to 18.44 that I measured). Still I don't see any logos like that on any TE connectivity items, so I'm hoping that one of you can save me from this wild goose chase that I've subjected myself to. I could buy them for 36 dollars for 10, but I would prefer to have more than that and the price is insane compared to the usual scumbags.
Edit: I linked to the wrong page on connectorexperts originally.
