Reed switch (also known as reed switch, magnetically controlled switch, etc.) is an electronic component that uses magnetic field to control its switch. When choosing and distinguishing the quality of reed switch, you can refer to the following aspects:
1. Material: reed switch is usually composed of metal reeds, magnetic materials and electronic components. Good reed switch should use high-quality metal reeds and magnetic materials to ensure switch performance and service life.2. Sensitivity: reed switchs sensitivity refers to its ability to sense changes in the magnetic field. A good reed switch should have high sensitivity in order to work reliably in different magnetic fields.3. Switching speed: The switching speed of reed switch depends on its magnetic material and design. High-quality reed switch should have fast switching speed to meet the needs of different application scenarios.4. Anti-interference ability: A good reed switch should have strong anti-interference ability to cope with the harsh working environment. For example, reed switch with strong anti-interference ability should be selected for application scenarios that need to work in high temperature, high humidity, high vibration and other environments.5. Working life: The working life of reed switch refers to the number of switches it can withstand under normal use conditions. A good reed switch should have a long working life to ensure good performance in long-term use.6. Safety performance: A good reed switch should have good safety performance, such as overload protection, short circuit protection and other functions, to ensure that other equipment will not be damaged or potential safety hazards will be caused under abnormal conditions.7. Stability: A good reed switch should have good stability, so as to ensure that there will be no performance degradation or failure in long-term use.8. Size and package: According to the actual application scenarios and requirements, select the reed switch with appropriate size and package. A good reed switch should have a good packaging process to ensure the reliability and stability of the product.
In a word, when selecting and distinguishing reed switch, we should pay attention to its material, sensitivity, switching speed, anti-interference ability, working life, safety performance, stability and size, so as to ensure that the selected reed switch can meet the practical application requirements.
