Does anyone have any information on the German DM 51 SAI?

The only thing I can find is at the bottom of this webpage ...

And this picture:

Janes states it is a Joint Denmark (NEA Lindburg) / German (ATLAS Elktronik GmbH) Project. Doing a little research I am wondering did Denmark make the fuze? On this website if you look at NEA Lindberg you see they primarily make fuzes for landmines. That would leave Germany to make the mine?

Any ideas or thoughts?
