Product description:
Reed switch
is a passive electronic component, which is widely used in various communication equipment. It is a line switching device controlled by a magnetic field signal, also known as a "magnetron". The outer shell is generally a sealed glass tube, in which two iron elastic reed electric plates are installed, and an inert gas called rhodium is also filled in the glass tube. Usually, the two reeds in the glass tube are separated. When a magnetic substance is close to the glass tube, under the action of the magnetic field lines, the two reeds in the tube are magnetized and attract and contact each other, so that the two pins are in contact with each other. connected circuit is connected. After the external magnetic force disappears, the two reeds are separated due to their own elasticity, and the line is disconnected. In practical applications, permanent magnets are usually used to control whether the two metal sheets are connected or not, so it is also called "magnetron".
Features:
1. The dry reed switch is compact in structure and light in weight, can be installed in extremely limited space, and 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:
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 tools are required.
2. The temperature and long exposure time may cause damage to the glass-metal seal (cracks, leakage, etc.), so fast and reliable welding technology (process) must be used. Recommended soldering conditions are: 280 to 300°C for hand soldering and 250 to 300°C for wave soldering.
