①It is used in aviation and aerospace technology to avoid collision of flying objects;
②In daily life, such as automatic doors in hotels, restaurants, and garages;
③In terms of security and anti-theft, such as data files, accounting, finance, museums, vaults and other important places, there are usually anti-theft devices composed of various proximity switches;
④In measurement technology, such as length and position measurement; in control technology, such as displacement, velocity, acceleration measurement and control, a large number of proximity sensors are also used.
Proximity sensor is a function set by using its sensing ability. It is also a new technology and new method. It is used in industry and agriculture, electronics industry, and pharmaceutical industry. It is also applicable because of its high temperature resistance and radiation resistance. Extremely strong, passable, the feeling of the surrounding temperature, the feeling of the surrounding objects, and the feeling of the same type of sensor, to produce influence and interaction, and it is also widely used in the occasion of the electrostatic capacity type.
