Metal encoder discs including stainless steel, nickel and copper, are used in industrial, military and aerospace applications where precision positioning is required. Photo etching is an economical
way to produce extremely small slot - as small as 0.004". Compared with other laser cutting, there is no burr and stress which will affect the durability and reading accuracy.
