Germany uses 230V, 50Hz with sockets and plugs Type C and Type F.
Sockets/plugs in Germany are completely different than in Saudi Arabia so you will need an adapter.
Frequency difference (60 Hz in Saudi Arabia vs 50 Hz in Germany) is generally not a problem - almost all items (except some types of clocks) will work on both and you shouldn't worry about it.
Germany also uses 230V as Saudi Arabia so you don't need a converter/transformer to convert a voltage as it's the same.
Sockets & plugs, frequencies and voltages are provided alongside the requirement for the adapter/converter if needed as well as compatibility across socket/plug type, frequency and voltage. Each socket/plug type has associated vector image.
Sockets & plugs category is available in production API version 2.
