The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-functionality, systemization, and networking. It not only promotes the transformation and upgrading of traditional industries, but also may establish new industries, thus becoming a new economic growth in the 21st century. point. Miniaturization is based on microelectromechanical systems (MEMS) technology and has been successfully applied to silicon devices as silicon pressure sensors.

The proximity sensor engineering project is a general term for sensors that do not require contact with a detection object for detection, instead of a contact detection method such as a limit switch.

The proximity sensor engineering project is a very important member of the sensor family and is widely used in industry. Although the price of a single proximity sensor is not very high, the general factory is in batch demand, so there is a large market for proximity sensors. When it comes to proximity sensors, everyone knows more famous brands like Turck, Omron, Balluff, etc. These sensor brands have occupied a large market for proximity sensors for quite some time.

In the past, domestic proximity sensor engineering projects mainly relied on imported brands such as Turck, Omron, and Balluff. The imported proximity sensors were not expensive enough to meet the needs of many customers because of their high price and long supply cycle. Many domestic factories hope to find domestic proximity sensors. In this case, many sensor manufacturers began to produce proximity sensors. At first, they imported foreign machines and talents to imitate imported proximity sensors. However, with the development of domestic sensor technology, there are already many proximity sensors of their own brands. To a large extent, it has been able to meet domestic needs.

At present, many factories in China use domestic proximity sensors or are trying to use domestic proximity sensors. Proximity sensors are no longer dependent on imported brands.
