Is there some magic to CPCs? There are lots of multipin connectors in all kinds of sizes out there. My personal favorite is Link's LK series. They are the most rugged connectors I've seen, and with the rubber collar and the roller bearing cam they are easy to use. The pins are very recessed for extra protection.

They are cheap and with the right backshell, pretty reliable as well.
AMP has a variety of shell sizes and pin configurations in the CPC series. While the most common in our world by far is the shell size 23 37-pin version, we have a few 16-channel snakes using the 52 pin insert in the same size shell.
