C-Family Protocol Heads were humanoid head parts for droids produced by Cybot Galactica, one of the two largest droid manufacturing companies in the galaxy. They were typical protocol style heads, equipped with binocular sensors and a cybot vocabulator—namely the TranLang III communications module. They were made of copper, titanium carbide and plastic, which means they were not magnetic. They had med-low material durability and weighed around 11 kilograms.
