Cybot Galactica C-Family Protocol Heads were humanoid head parts for droids. They were typical protocol style heads, equipped with binocular sensors and a cybot vocabulator (namely the TranLang III Communicator module). They were made of copper, titanium carbide and plastic, which means they weren't magnetic. They had med-low material durability and weighed around 11 kg. Those heads were part of the famous 3PO-series, and presumably its offshoots like the 3PX-series or TC-series.
