A, magnetic switch is what
Magnetic proximity switch is a kind of proximity switch. Proximity switch is one of the many types in the sensor series. It uses an advanced electromagnetic working principle and is a position sensor. It can change the positional relationship between the sensor and an object and convert non-electrical or electromagnetic quantities into the required electrical signals for control or measurement.
Magnetic proximity switches are used in aerospace, aerospace and industrial applications. In everyday life, such as automatic doors in hotels, restaurants, garages, using automatic heaters. In security and theft, e.g. data files, accounting, finance, museums, treasury, etc., it is often equipped with anti-theft devices consisting of various proximity switches. In measurement technology, such as length, position measurement; in control technology, such as displacement, speed, acceleration measurement and control, also use a large number of proximity switches.
Two, what is the principle of magnetic 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, the ring magnet is located in the interior, the floating ring is controlled by a fixed ring. The float floats up and down within a range of positions associated with the reed switches. The magnets within the floats are used to attract the contacts of the reed switch to produce an opening and closing action.
Three, the principle of magnetic switches - what are the classifications of magnetic switches
SMC magnetic switches can be divided into contact and non-contact, a series of magnetic switches, there is no sign or A, B, C, E, Z is the touch type, F, G, H, J, K, M, P, Y is the non-contact type. Contact types exist that have no leakage current. Non-contact magnetic switches have a semi-permanent life because there are no movable members, but leakage current exists.SMC magnetic switches are also available in two-wire, three-wire (also divided into two types: NPN and PNP), and four-wire (less commonly used). In addition, the standard wire length for magnetic switches is 0.5 meters. But you can also choose 3 meters or 5 meters.
