[RE-wrenches] Amphenol Connectors

[Jim Duncan]

Several years ago I disassembled an Amphenol and a MC4 connectors to 
find for myself what the difference was. It came down to the cross 
section of the O-ring. One brand was smaller than the other. Also the 
female component that the O-ring fit into was correspondingly different.
So in one assembly the fit was too tight but both mismatched pieces 
would go together with extra effort while the other the o-ring did not 
fit tight enough and would snap together with normal pressure. It's been 
a number of years since I did this but I doubt that either manufacturer 
would alter anything that would make new connectors not compatible with 
older ones.
I also recall that MC was on a tear for years, especially at trade 
shows, confronting any unauthorized competitor connector maker that 
implied that theirs were compatible with MC products.
