Yes, the connectors are AMP. Here is what I got back from Tyco/AMP when I
made an inquiry about them:

Hello,

The item you are questioning was obsoleted in 1997 with no replacements. I
do not find anything similar to this item nor do we show any stock left in
inventory. I do not see where any distributor has any inventory either. We
would not be able to offer a solution unless you can change you design to
one of the other Commercial MNL products.

Have a good day.

I am looking for a small number of mate-n-lock (1-480459-0) male
plug shells (about 24) and associated male pins. Is there any chance
that there are still some available? Your catalog listing shows them
as obsolete.
