KY-021 Mini Magnetic Spring Sensor Module
Product Description:
Reed switch is the abbreviation of dry reed. It is a passive electronic switch element, and has the advantages of simple structure, small size and easy control. Its shell is a sealed glass tube, and the tube is installed with two iron elastic reed, but also filled with rhodium metal inert gas. In ordinary times, the glass tubes in the two reeds are made of special materials separately. When the magnetic material is close to the glass tube, under the action of the magnetic field line, the pipes in the two reeds are magnetized to attract each other to contact, and the reeds will attract together to make the connection points of the connecting circuit communicate. After the outer magnetic reed disappears due to its flexibility and separation, the line is disconnected. Therefore, as a line switch device controlled by magnetic field signal, reed tube can be used as a sensor to count the number, spacing, etc. (mainly used in the production of door magnet and magnetic window in the safety system), and also widely used in various communication devices. In practical use, permanent magnets are usually used to control whether two metal plates rotate
