Tunze 904 magnet question

I have recently obtained a new Tunze 9004 skimmer for my custom AIO tank.
I am trying to decide whether it is safe for outer magnet to be submerged in saltwater.

Does the outer and inside magnet have different safety levels for rusting?

Magnets seem to belong to the third generation with the blue silicon ring and smooth coating.
They do not have "double plates" that second generation seem to have.
New Tunze 6015 and 6040 also have the same magnet structure is that correct?

Thank you
