Best Multi-pin Connectors

[RVG8tor]

I was looking over the ICOM radio I have and it has parts to make the connection with a MOLEX type connector. This got me to thinking what most guys think are the best type of connectors for multi-pin connections, molex, D-sub,..? I am not even close to my panel work but I am laid up and can't build so to keep my mind in the project I have come up with this question. I want to set up the radio in the shop.

Molex, made by AMP work fine, I really like the gold pin crimp sub-D's but your limited by wire gauge. My entire air frame is set up using Sub-D and AMP connectors....Everything so far has been "smoke" free.

I link the AMP Circular Plastic Connectors (CPC). They are readily available from Mouser.

Similar to the AMP CPC ones mentioned above are the Conxall ones - also available from Mouser.
These are good for smaller bundles, and are ideal for trim servo cables. The bulkhead mount versions can give you more options for location.

Remember, each connector you use should be different to prevent accidental misconnections.....

Ahh, connectors. One of any good geek's favorite things. I'm guilty. I've been using "Microfit 3.0" in many low current locations. I have the production crimp tool that makes installation just so easy I have to have a reason to use something else. I'll probably experiment with some of the others mentioned here in the next build just for fun.

Scott's right. A very rewarding discussion for the inner geek.

I hate Molex. I have personally seen unacceptable failure modes in heavy truck (parking brakes at speed) using molex connectors, manufacted by AMP.

Packard 150 metri-pack series for powering stuff and Deutch DT or DTM sealed for anything under the cowl and signal level stuff. Digi-key, mouser, wherever - in my case, it means the supply cabinet in the lab . In any case, they always have a positive mating lock, and can be saftied with a zip-tie. Generally, they all have secondary pin locks as well.

Regardless, strain relief is the best thing you can do for connector reliability, IMO.
