Product Detail

Plastic encapsulated reed switch

It is composed of a pair of elastic reeds made of magnetic materials, which are sealed in a glass tube filled with inert gas. The end faces of the reeds overlap each other but leave a thin gap. The reed face contacts are plated with a precious metal such as rhodium or ruthenium, which gives the switch a stable characteristic and an extremely long service life.
When the magnetic field generated by the permanent magnet or coil is applied to the switch, the two reeds of the reed switch are magnetized, so that one reed generates an N pole at the contact position, and the other reed generates an S pole at the contact position. . If the generated magnetic field attraction overcomes the resistance produced by the elasticity of the reed, the reed is contacted by the attractive force, that is, the circuit is closed. Once the magnetic force is removed, the reeds are separated again due to the elastic force, that is, the circuit is disconnected.
In a closed metal or plastic tube, set one or more magnetic reed switches, and then pass the tube through one or more floating balls that are hollow with ring magnets inside, and use a fixed ring to control the floating ball and the magnetic reed The switch is in the relevant position to make the float float up and down within a certain range. The magnet in the float is used to attract the contacts of the reed switch, and the action of opening and closing is generated.

Precautions:
1. The supply voltage must not exceed the range of the reed switch, otherwise the core components will be damaged.
2. When the reed switch is welded, it cannot be dropped or knocked, otherwise it will cause the reed switch to break and lead to failure.
3. There should be no other magnetic things around the reed switch, otherwise it will affect the normal connection or disconnection of the switch.
installation method:
1. Usually, the reed switch is welded with wire.
2. Another is to solder the plastic reed switch on the PCB board.
