Reed switches (also known as reed switches, magnetic switches, etc.) are electronic components that use a magnetic field to control switches. When selecting and distinguishing the quality of a reed, the following aspects can be considered:

1. Material aspect: Reed tubes are usually composed of metal springs, magnetic materials, and electronic components. A good reed should use high-quality metal springs and magnetic materials to ensure switch performance and lifespan.

2. Sensitivity: The sensitivity of a reed switch refers to its ability to sense changes in magnetic fields. A good reed tube should have high sensitivity to work reliably in different magnetic field environments.

3. Switching speed: The switching speed of a reed depends on its magnetic material and design. High quality reed tubes should have fast switching speeds to meet the needs of different application scenarios.

4. Anti-interference ability: A good reed should have strong anti-interference ability to cope with harsh working environments. For example, for application scenarios that require working in environments such as high temperature, humidity, and vibration, it is recommended to choose those with higher performance

A reed with strong anti-interference ability.

5. Working life: The working life of a reed is the number of times it can withstand switching under normal usage conditions. A good reed should have a longer working life to ensure good performance during long-term use

Can.

6. Safety performance: A good reed switch should have good safety performance, such as overload protection, short circuit protection, etc., to ensure that it will not damage other equipment or cause safety hazards in abnormal situations.

7. Stability: A good reed should have good stability to ensure that there will be no performance degradation or failure during long-term use.

8. Size and packaging: Select the appropriate size and packaging of the reed according to the actual application scenario and requirements. A good reed tube should have a good packaging process to ensure the reliability and stability of the product.

In summary, when selecting and distinguishing reed contact switch, attention should be paid to their material, sensitivity, switching speed, anti-interference ability, working life, safety performance, stability, and size to ensure that the selected reed switch can meet the requirements of actual application requirements.

What is a reed switch?

Simply put, a reed switch is an electrical switch or sensor

The term "magnetic reed switch" can refer to either the small glass electronic components shown in the above figure, or the complete components based on it, or similar types of electronic components. On this page, "reed switch" will be used to refer to the component itself and its overall function. But in general, for reed switch assemblies, the same is true for complete assemblies. Magnetic reed switches are also commonly referred to as magnetic switches, magnetic sensors, proximity switches, or proximity sensors.

What is the application of magnetic reed switch?

Magnetic reed switch

Magnetic reed switch (dry reed) has been widely used in home appliances, automobiles, communications, industry, medical treatment, security and other fields. Below, we will explain the application of magnetic reed switch in magnetic reed relay and dry spring sensor.

Magnetic reed relay

Place a magnetic spring switch around the coil so that the coil through which the current passes is equivalent to the magnetic field generated by a permanent magnet.

A coaxial shield is placed around the switch to switch the high-frequency signal to 20GHz.
Because the dry spring switch has no wearing parts, the contact can switch the low-level signal.
Dry spring relay is widely used in the whole field of testing and measurement.

Test system, matrix, RF, modem, alarm, very suitable for magnetic reed relay:

1. High cycle count
2. High voltage applications
3. Low current, low voltage switch

Dry spring sensor

Using the magnetic spring switch, the dry spring sensor can sense that all kinds of movement adopt permanent magnets.
Dry reed switches draw zero current when they are on, which makes them an ideal choice in energy-saving equipment applications.
Even when air, plastic and metal are separated, magnets can be applied.
Magnets and reed switches are generally separated by physical enclosures or other obstacles.

Dry spring sensor is used to detect movement, count, detect liquid level height, liquid level measurement, switch, implant equipment in harsh environment, etc.
