The role of magnetic sensing switches
A magnetic proximity switch is a type of proximity switch. A proximity switch is one of the many types in the sensor family. It uses an advanced electromagnetic working principle and is a position sensor. It can change the positional relationship between the sensor and an object in order to convert a non-electrical or electromagnetic quantity into a desired electrical signal for control or measurement purposes.
Principle of Magnetic Induction Switches
Magnetic switches are closed metal or plastic tubes which are provided with one or more reed switches, and then the tube is inserted through one or more floats, with internal ring magnets, and the floats are controlled by a stationary ring. The float floats up and down within a certain range at the relevant position of the reed switch. The magnets within the floats are used to attract the contacts of the reed switch to produce an opening and closing action.

How to install magnetic inductive switch?
1, sensor switch can be divided into 86 type sensor switch and ceiling type sensor switch.
2. The size of 86 type sensor switch is the same as the traditional mechanical wall switch, which can directly replace the original wall switch.
3. Ceiling-mounted sensor switches are installed in a similar way, taking BR-306C as an example. Open a hole with a diameter of 60mm on the ceiling. four terminals L, N, LOUT, NOUT are connected to the fire wire in, zero wire in, fire wire out and zero wire out.
After connecting the wires, the switch can be snapped into the ceiling; if there is no installation environment for the ceiling, you can first lock the switch top box to the top with a twisted pair of wires and then screw the switch into the bottom box.
4, because the left and right sides of the switch sensing range is greater than the top and bottom sides, so when installing the switch, the positive axis should be perpendicular to the direction of the human walking channel, in order to get a better sensing effect.
5. After installing the switch, the power will be turned on. When the ambient light is sufficient, the bulb will flash three times. After one minute, the initialization is finished. The switch enters the monitoring state and the ambient light is blocked by the object to make the switch work.
6. After installing the switch, the power will turn on. When the ambient light is insufficient, the switch enters the monitoring state directly. If the person has not left and is active, the switch will continue to work.
7, if you are not satisfied with the delay time or material photosensitivity value, you can use the back of the 86 type wall switch to adjust the time, the former adjusts the delay time, the latter adjusts the light sensitivity value. Twist gently, not too hard.
The above is what I have organized for you today about the magnetic induction switch some of the content, in the purchase of building materials, I recommend that you visit the building materials market, to find the most suitable for you. I hope the above content can bring a little help to friends in need, thank you for reading.
