                                      Stainless Steel Optical Encoder Discs

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.

Photo etched encoder discs are commonly used in CNC machines, robots and other industrial equipment. Photo etched discs provides precise shaft rotation economically and effectively.
grow your business with chemical etching

Advantages of Photo Etching:

•Low tooling cost, no need for expensive DIE/Mould
•Can fabricate more thinner metals(T=0.02-1.2 mm)
•No alteration process, the characteristics can be obtained as the designer intended
•High accuracy
•Various apertures, shapes and bar combinations
•Burr & Stress free manufacturing method
•Prototypes – fast turnaround to meet your needs
