The dry reed pipe is short for dry tongue reed pipe. It is a passive electronic switching element with contacts. It has the advantages of simple structure, small size and easy to control. Its shell is generally a sealed glass tube. There are two iron elastic reed electric plates, also filled with an inert gas called metal rhodium. Usually, the two reeds made of special materials in the glass tube are separated. When a magnetic substance is close to the glass tube, under the action of magnetic field lines, the two reeds in the tube are magnetized to attract and contact each other, and the reeds will be attracted together to connect the circuit connected to the node. After the external magnetic force disappears, the two reeds are separated due to their own elasticity, and the line is disconnected. Therefore, as a line switching device controlled by a magnetic field signal, the reed can be used as a sensor for counting, limit, etc. (mainly used in the production of door magnets and window magnets in security systems), and also It is widely used in various communication devices. In actual use, a permanent magnet is usually used to control the connection of these two metal pieces, so it is also called "magnetron".
Features and applications of reed switch:
1. The dry reed pipe has a compact structure and small weight, can be installed in an extremely limited space, and is very suitable for miniaturized equipment.
2. The switch components of the dry reed pipe are hermetically sealed in an inert gas atmosphere, and will never be in contact with the external environment, and have a long working life.
3. The dry reed tube does not use sliding elements, so there will be no metal fatigue related to the degradation of all metals, ensuring that there is virtually no limit to the mechanical service life.
4. Magnetic reed switches are widely used in mobile phones, program-controlled switches, copiers, washing machines, refrigerators, cameras, disinfection cupboards, door magnets, window magnets, electromagnetic relays, electronic scales, liquid level gauges, gas meters, water meters, etc. Good application.
Precautions for using reed switch:
1. Extreme care must be taken when cutting or bending the lead pins of the reed switch to avoid improper stress and damage to the glass-metal seal. Appropriate clamping tools must be used
2. Encounter temperature and long exposure time may cause damage to the glass-metal seal (cracking, leakage, etc.), so fast and reliable welding technology (process) must be used. The recommended welding conditions are: 280 to 300°C for hand welding and 250 to 300°C for wave welding.
