Encoder reading head chips are used in the field of optical encoder chips. For a long time, the sensor chips required by our country need to be imported from abroad, especially in high-end applications. Foreign manufacturers package and sell the entire encoder to our country, rather than selling such encoder chips separately. At present, in the fields of CNC machine tools, medical devices, industrial robots, precision measurement equipment, etc., especially in the high-end demand of these fields, we have a large demand for optoelectronic encoders. If we cannot achieve breakthroughs in optoelectronic encoder chips, the development of these industries will inevitably face the risk of being stuck. Moreover, integrated circuit technology is the most complex process in human history that has developed to the present day. It is the result of collaboration among thousands of enterprises around the world. To achieve domestic breakthroughs in the field of high-end optical encoder chips, there is a long way to go.

 

At present, the international market is experiencing a chip shortage, with the production cycle of some high-end optical encoders reaching 16 weeks. The main reason is the insufficient supply of core chips. Looking at the current field of optical encoder chip manufacturing in the world, this article summarizes a directory of chip manufacturers from various countries, providing a comprehensive understanding of the field of optical encoder chips.

 

Optical encoder reading head chip manufacturers are mainly concentrated in the United States, Japan, and Germany.
