This is a two pin, locking style connector with "AMP" molded into the front edge; there is also a "P".
Material is nylon or similar and the pins are pushed in from the rear like Molex connectors.
What is "unusual" is the D shaped profile of the "nose" – close but not compatible with other two pin connectors I can easily obtain 🙁
AMP/Tyco never got back to me and our usual distributors are clueless.
We have a few thousand machines in service with 24 volt power supplies that use this connector (manufacturer of the power supplies is HIPRO – now under new ownership – also not communicating)
Have spent a week trawling through connector catalogs, waited a couple of weeks for Tyco and the power supply folks to get back to me… a bit frustrating.

That connector family is called the Mate-n-Lok series. They are great power connectors and have been around for years. They come in two general sizes, the Mini type and the standard or Universal series.
Here is a link to the Mouser catalogue page for the Mini.
Your two pin is hard to tell from the picture if it is the universal or the mini.
