When selecting a reed switch for a specific application, one of several issues to be considered is to determine how much load current the switch needs to handle. If only the low current signal is switched, there is no problem, because almost any reed switch can handle at least 100mA of current

Reed switch is a passive electronic component, which is widely used in various communication devices.

Generally, the failure rate of relay is set at 50ppm, so to meet this requirement, the quality level of reed switch is much higher than the requirement of 50ppm. Up to now, no electromechanical device has reached such a quality level.

Reed switch, also known as reed tube or reed switch, is a kind of magnetic sensitive special switch and the main component of reed relay and proximity switch.

The sensor is mainly a kind of detection device, which can feel the measured information, and then transform this signal into the form of electric signal or other required forms for output according to certain rules.

Today, lets explain where reed switch is used and what role it plays.

Imported reed switch is a kind of passive electronic switch element with contacts, which has the advantages of simple structure, small size and easy control, etc.

Next, lets take a look at two ways about reed switch.

The AT value of reed switch is generally tested by reed switch tester. The AT value of the reed tube generally refers to the ATtraction value of the reed tube, which means that the contacts in the reed tube act after the induction value of the magnetic force (in gauss) corresponding to the at value

When installing reed switches, soldering or welding is usually used. If the installation side (including its vicinity) is non-magnetic, it will have no influence on the movement. If it is a magnetic body, the action characteristics will change. Therefore, the installation must be confirmed before u

Reed switch can be used as a sensor for counting and limiting. For example, there is a bicycle kilometer meter, which is formed by sticking magnets on tires and fixing reed switch on one side. Install the reed switch on the door, which can be used as an alarm when opening the door. Besides, it can
