Let me know if this question violates the no specific product rule, but I am hoping someone can suggest a connector for me.

I need a connector/family of connectors with: at least 6 pins, but not more than 12. can carry at least 2 amps per pin. has solder cups big enough for 18 gauge wire. positive connection like a thread or clip. 6x18 gauge cable strain relief size. and a perk would be a split style housing/strain relief like a DE-9.

I think my optimal connector would be a 6 pin military style screw on connector from Amphenol, but at ~$60 per connector it might be too expensive for our project as we need 8 separate connections.

What might work for me?

There are plenty of options out there, the final choice depends on your requirements: do you want environmental protection, EMI shielding, high speed data, etc. For "general purpose" low voltage/low speed data, take a look at M12 connectors though 18 AWG wire might be hard to find in a 6+ pin configuration. Parametric search on Digikey will show you several attractive prospects in your price range.

There's also the MIL-derivative 5015 family of connectors which are probably going to be cheaper than 38999s but they're a real pain to work with.

For up to 8 circuits, consider the DC-8W8 D-sub connector (my site).

There are no D-sub connectors for more than 8 power circuits. Therefore, I suggest you switch to circular connectors. For 12 circuits, consider the Weipu SY21 circular connector (my site).
