Whether it is a speeding high-speed rail or a transformer of four or five hundred tons, the heavy equipment of a great country has always been enviable. First of all, from the head, it gives a stunning feeling. And the unit price is often not low, a large boiler of 1 million kilowatts is worth several hundred million.

In contrast, sensors are a troublesome industry. As a marginalized component industry, it is one of the accessories of great power equipment. Although it is difficult to move the heavy weapon without it, it is a natural king of supporting roles, always staying out of the light. When it comes to the characteristics of the order, the master of the manufacturing process will also look helpless. There are more than 50,000 varieties of sensors in the world. A factory may need to produce hundreds of models, and many orders are often calculated in thousands. Or there are only hundreds, dozens, or even a few, typically small batches and multiple varieties. The technology is difficult, the order is very complex, the value is very small, and the fields are many and complicated. There is no doubt that the sensor is a hard industry.

However, Chinese manufacturing always has to face difficulties, and sensor companies need to choose their own breakthrough path.
