The function of the magnetic switch The principle of the magnetic switch
Magnetic switches are 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 standards for different countries, the magnetic switch symbol is also different, so everyone should pay attention to which country is marked when viewing related information. Next Xiaobian introduced the function of the magnetic switch and the principle of the magnetic switch. The role of magnetic switch Magnetic proximity switches are one type of proximity switches. Proximity switches are one of many types of sensors in the family of sensors. They are based on electromagnetic working principles and are manufactured using advanced technology. They are position sensors. It can change the positional relationship between the sensor and the object, convert the non-electricity or electromagnetic quantity into the desired electrical signal, so as to achieve the purpose of control or measurement. Magnetic proximity switches have a wide range of applications in aerospace, aerospace technology and industrial production. In daily life, such as automatic doors for hotels, restaurants, and garages, there are applications on automatic hot air blowers. In terms of security and anti-theft, such as data files, accounting, finance, museums, treasury and other places, are usually equipped with anti-theft devices composed of a variety of proximity switches. In measurement technology, such as length, position measurement; in the control technology, such as displacement, velocity, acceleration measurement and control, also use a large number of proximity switches. The principle of magnetic switch The magnetic switch is in a closed metal or plastic tube, and is provided with one or more reed switches, and then the tube is passed through one or more, hollow and floating balls with ring-shaped magnets inside, and the floating ring is controlled by using a fixed ring. With the reed switch in the relevant position, the floating ball floats up and down within a certain range. The magnet in the float ball is used to attract the contact of the reed switch, and an on and off action occurs. Classification of SMC magnetic switches SMC magnetic switches can be divided into contactless and non-contact two. SMCD-? series of magnetic switches, there is no mark or A, B, C, E, Z for the touch type, F, G, H, J, K, M, P, Y are non-contact type. There is no contact leakage current. The non-contact magnetic switch has semi-permanent life because of no moving parts, but there is leakage current. SMC magnetic switch can also be divided into two-wire system, three-wire system (also divided into NPN, PNP two), four-wire system (less used). In addition, the wire length of the magnetic switch is 0.5 meters. But you can also choose 3 meters or 5 meters. Magnetic Switch Brand 1.
