Taking China as an example, the transformation and development of CNC machine tools has been rapid. Various types of CNC machine tools produced every year require a large number of optical encoders. At the same time, the development of new energy vehicle manufacturing, healthcare and other industries in Asia has also significantly promoted the growth of the optical encoder market.
Product technology is constantly updated: Manufacturers integrate embedded microprocessors and advanced signal processing algorithms into encoders, which improves operational reliability and reduces the mechanical complexity and vulnerability of traditional absolute optical encoders when used under harsh conditions. Microprocessor-based instruments can also change measurement characteristics through software, such as updating resolution and measurement direction, without mechanical or physical changes. Technological innovation has expanded the application scenarios of optical encoders, thereby increasing market demand.
Limited use environment: Optical encoders are complex electronic devices composed of integrated circuits, LEDs, photodetectors, etc., which are easily damaged by electrical interference. Its main component, the thin glass disk, is easily damaged when subjected to excessive shock or vibration, and has certain requirements for the operating temperature. In dusty and dirty environments such as industry, contaminants will accumulate on the code disk, affecting the projection of LED light to the optical sensor, causing the square wave signal to be interrupted or completely lost, seriously affecting the reliability and accuracy of the encoder, and limiting its scope of application.
3 Technological Innovations in the Optical Encoders Market
Integrated technology improves performance: Manufacturers actively integrate embedded microprocessors and advanced signal processing algorithms into encoders, significantly improving product performance. Through this integration, the operational reliability of encoders is improved, reducing the mechanical complexity and vulnerability of traditional absolute optical encoders under harsh conditions. With the help of microprocessors, engineers can flexibly change measurement characteristics through software, such as adjusting resolution and measurement direction, without making complex mechanical or physical changes to hardware, which greatly expands the application scenarios of optical encoders.
Chip technology improves accuracy: The chip technology of optical encoders continues to advance, using optoelectronic chips composed of photodiode arrays, high-precision low-noise operational amplifiers, secondary fixed gain amplifiers, and hysteresis comparators with post-differential, with an accuracy of up to 23 bits. This chip can effectively eliminate the impact of environmental factors such as LED light emission changes with temperature, LED aging, oil and dust contamination of the code disk, and low surface cleanliness of the detector on the encoder reading, thereby improving the repeatability and positioning accuracy of the encoder and promoting the development of products towards intelligence and high precision.
