Proximity switches, as a type of switch sensor (i.e., contactless switches), have the advantages of long service life, reliable operation, high repeatability, and no contact. With characteristics such as mechanical wear resistance, no sparks, no noise, and strong shock resistance, it has wide applications in aviation, aerospace technology, industrial production, and daily life. application. Proximity switches are essential in intelligent manufacturing and are commonly used in intelligent manufacturing processes such as production line inspection, stack height detection, and liquid level detection. In manufacturing scenarios, proximity switches are used as the core of product inspection solutions to replace contact-based inspection methods such as limit switches in production equipment. This method allows for efficient testing without contact with the object being tested, effectively reducing quality risks during the testing process and ensuring safe and reliable testing. Pollution is eliminated, ensuring a high yield rate; at the same time, it can shorten the production cycle and improve production efficiency.
