I have tried a couple of sensors so far:

AI006Autosen20mm40x40Not working
E2B-M30LN30-WP-B1 2MOmron30mmM30No working

The only one working in a reliable manner is the AI007. This is not only because of the bigger range but also because it is less sensitive to the metal plate on the side of the door frame which caused interferences with the Omron one.

The best solution would be to use a shielded sensor but I've not been able to find one with such range or are way too expensive.
