The sensor has a high degree of specialization, with a complete range of sensors except international first-line manufacturers. The remaining companies are basically concentrated in a certain segment. For example, some companies mainly produce sensors suitable for power industry, some companies mainly produce sensors suitable for automobile industry and electronic consumption, and some manufacturers only produce one or several sensors. This situation makes it very troublesome for some demanding customers to buy sensors. For example, if some customers need to purchase multiple sensors, they need to contact multiple sensor manufacturers, and the product model matching of different manufacturers will also bring trouble.
At present, China's high-end sensor field is in the stage of technical research, that is, the market threshold is about to break through. Some domestic enterprises have introduced foreign advanced technology and made some breakthroughs in the fields of proximity sensors, photoelectric sensors, infrared sensors, speed sensors and acceleration sensors, but they have not yet formed a scale. However, I believe that with the support and promotion of national policies, the sensor industry in China will achieve rapid growth.
