Reed switch specification parameter table:
Reed switch is the abbreviation of dry reed switch. It is a passive electronic switch element with contacts. It has the advantages of simple structure, small size and easy control. Its shell is generally a sealed glass tube, which is installed in the tube. There are two iron elastic reed plates, and an inert gas called metal rhodium is also filled. Usually, the two reeds made of special materials in the glass tube are separated. When there is a magnetic material close to the glass tube, under the action of the magnetic field lines, the two reeds in the tube are magnetized and contact each other, and the reeds will be attracted together, making the circuit connected to the node connected. 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 switch device controlled by a magnetic field signal, the reed switch can be used as a sensor for counting, limiting, etc. (mainly used in the production of door magnets and window magnets in security systems). It is widely used in various communication devices. In practical applications, permanent magnets are usually used to control the connection of these two metal sheets, so they are also called "magnetrons".
Reed Switch Features and Applications:
1. The dry reed switch is compact in structure and light in weight, and can be installed in extremely limited space, which is very suitable for miniaturized equipment.
2. The switch components of the dry reed switch are hermetically sealed in an inert gas atmosphere, which will never come into contact with the external environment and have a long working life.
3. The dry reed switch does not use sliding elements, so there will be no metal fatigue phenomenon related to all metal degradation, ensuring virtually unlimited mechanical service life.
4. Reed switches have been widely used in mobile phones, program-controlled switches, copiers, washing machines, refrigerators, cameras, disinfection cupboards, door magnets, window magnets, electromagnetic relays, electronic weighing instruments, liquid level gauges, gas meters, water meters, etc. good application.
Precautions for the use of reed switches:
1. Extreme care must be taken when cutting or bending the lead pins of the reed switch to avoid damaging the glass-to-metal seal by applying undue stress. Proper clamping tool is a must
2. The glass-to-metal seal may be damaged (cracks, leaks, etc.) when exposed to temperature and prolonged exposure time, so fast and reliable welding techniques (processes) must be used. Recommended soldering conditions are: 280 to 300°C for hand soldering and 250 to 300°C for wave soldering.
