Glass encoding disk : incremental encoder disk & reflection code disc

Metal encoding disk

The metal code disc is produced by etching process.

Conventional: 100/200/256/300/360/400/500/512/600/720/800/1000/1024/1200/2000/2048 and other pulses.

The metal code disc is generally: 100-1024 pulses, which are generally determined according to the outer diameter of the code disc and the thickness of the metal material. In CG, 2048 pulses can be achieved. Due to the high precision of 2048 and above, most of the glass code discs are used, but the concentricity, fragility, and high cost of glass code discs are far less than that of metal code discs. (Film code disc can also be achieved, but considering that its stability, accuracy and service life are far less than metal and glass, it is not recommended to use).

Material selection of metal code disc: generally use sus304 imported material from Japan, thickness 0.05/0.08/0.1/0.15/0.2, etc.

Requirements: CG conventional tolerance +-0.01mm, the aperture part is uniform and free of burrs.

Of course, the number of pulses of the mechanical code disc is low, the thickness and hardness are high, and special products also need to have special requirements and production processes

Optrytech Optics can provide materials of glass, film, metal, provide samples, can customize conventional pulse line pairs 256 lines, 500 lines, 1000 lines, 2400 lines, 3600 lines, 5000 lines, etc. Can be customized.
