Heavyweight EV Heads were head parts for droids made by Industrial Automaton. They were reinforced helmets made of malleable cast iron, copper and plastic, equipped with wideangle visual sensors and cybot vocabulator. They also furnished with a broadband antenna, a high-frequency binary comlink, and speech mimic flap.
These heads had high material durability and weighed around 35 kg. These components were part of the infamous EV-series supervisor/interrogator droid.
