Encoding disk refers to a digital encoder that measures angular displacement. It has the advantages of strong resolving power, high measurement accuracy and reliable work. It is one of the most commonly used displacement sensors for measuring the position of the shaft rotation angle. The code disk is divided into two types: absolute encoder and incremental encoder. The former can directly give the digital code corresponding to the angular position; the latter uses a computing system to make the pulse increment generated by the rotating code disc against a certain reference number addition and subtraction. The metal encoding disk is directly engraved with through and unconnected lines, and it is not fragile, but because the metal is not easy to corrode but easy deform, the accuracy is limited, and its thermal stability is an order of magnitude worse than that of glass. SUS304 Stainless Steel Encoder Grating is an important part of encoder, its mainly used in motor, hardware, electrical appliances, automobile and other fields. 

We customize diverse patterns metal encoder disk with drawings provided by customers. We are equipped with professional metal etching equipment and exposure development equipment. The raw material use for encoder disk are SUS304 stainless steel and the flat degree can below 0.02 mm. Our etched and produced encoder can be available in harsh environment and can achieve the standards of no burr and flat degree below 0.02.

Below are the specific parameters of this product, please check more Encoder Parts in our website for more ideas.
