Magnetic switches are very common in industrial production. For example, the function of testing the position of the cylinder piston is widely used in industrial production. There are also different national standards, and the magnetic switch symbols are also represented differently, so everyone should pay attention to which country is marked when viewing relevant information. Next, please follow us to learn something about magnetic induction switches.
The role of magnetic induction switch
The magnetic proximity switch is a proximity switch. Proximity switches are one of many types in the sensor family. It adopts advanced electromagnetic working principle and is a position sensor. It can change the positional relationship between the sensor and the object to convert non-electrical or electromagnetic quantities into the required electrical signals for control or measurement purposes.
Principle of magnetic induction switch
A magnetic switch is a closed metal or plastic tube equipped with one or more reed switches, and then the tube is inserted through one or more float balls, There is a ring magnet inside, and the floating ring is controlled by the fixed ring. At the relevant position of the reed switch, the float floats up and down within a certain range. A magnet within the float is used to attract the contacts of the reed switch to create an opening and closing action.

How to install a magnetic induction switch?
1. Sensor switches can be divided into type 86 sensor switches and ceiling-type sensor switches.
2. The size of the 86-type sensor switch is the same as that of the traditional mechanical wall switch and can directly replace the original wall switch.
3. The installation method of the sensor switch installed on the ceiling is similar, taking BR-306C as an example. Open a 60mm diameter hole in the ceiling. The four terminals L, N, LOUT and NOUT are connected to the live incoming line, neutral incoming line, live wire outgoing line and neutral outgoing line.
After connecting the wires, the switch can be buckled 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, and then screw the switch into the bottom box.
4. Since the sensing range on the left and right sides of the switch is larger than the upper and lower sides, when installing the switch, the positive axis should be perpendicular to the direction of the walking channel in order to obtain better sensing effects.
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 completed.
The switch enters the monitoring state, and the ambient light is blocked by objects, causing the switch to work.
6. After installing the switch, turn on the power. When the ambient light is insufficient, the switch directly enters the monitoring state. If the person does not leave and is active, the switch will continue to work.
7. If you are not satisfied with the delay time or material light sensitivity value, you can use the back of the 86-type wall switch to adjust the time. The former adjusts the delay time, and the latter adjusts the light sensing value. Twist gently, don't use too much force.
