Last update 22 Feb 2021

This is just a short summary of a subset of the MIL-style connectors that we commonly use. It’s by no way complete or guaranteed to be correct - it’s used as a selection help in case I’m deciding on the proper connector or at least connector category to use for a given application.

Norm Class Locking Waterproof Gender Usage area Contamination Vibration and Schock Comments
MIL-DTL-12520   Centerlock screw lock waterproof hermaphroditic ground, shore dust, dirt, water resistant Vibration and schock resistant (secured via wing-blade handle)  
MIL-DTL-22992 C Threaded waterproof hermaphroditic vans, shelters, trailers, buildings, heavy duty applications waterproof Quick disconnect
