Thanks David,
I used a flyer from Assmann connectors which is also not very clear. Mini-DIN connectors have up to 8 pins in two rows equally spaced 2.5mm in X and Y axis. The question is still if a four pin connector uses two rows or one with four pins in line omitting the second row.
There are also three different versions: unshielded, partly shielded and fully shielded with extra ground connections to the body.
I attached the package (as I imagine it should be) for a fully shielded 4 pin connector.
