(1) Nau'in injiniyan: dan wasan ya kore shi, masarufi, camps, da sauransu.
(2) Nau'in Lantarki: Ya ƙunshi masu son wutar lantarki, Amplifiers Gudanarwa, Masu Bincike da alamomi masu saiti. Tana hada ayyuka masu aminci kamar nuna, sarrafawa da ƙararrawa. Lokacin da crane ta ɗaga kaya, firikwensin a kan bangariyar da ke cikin niyya, sai ya canza nauyin kaya zuwa siginar lantarki, sannan kuma ya yanke shi don nuna darajar kaya.
