Hi, Javier. I'm sorry, but I have the older Samsung Galaxy Tab 1. The adapter is perfect, but you may want to check with Samsung to find out if it will work with the Tab 2. Try this: http://www.samsung.com/us/mobile/galaxy-tab Suerte.
No it will not work with the 5100 or 5110 series tabs. Only with the 5113 US wireless tab. They just came out with a new adapter for 2013 but have not heard any reports of it fixing the compatability issue with the 5100 5110 series tabs.
