Normally open explosion-proof magnetic proximity switch LKG-48V-YQFR Product description: Magnetic switch means induction through a magnet, which is a magnet. There are several types of magnets, including rubber magnets, permanent magnet ferrite, sintered neodymium iron boron, etc. commonly used in the market. The switch is just a dry pipe. Dry tongue tube is the abbreviation of dry tongue tube, which is a passive electronic switching element with contacts. It has a simple structure and small volume, making it easy to control and other points. Its outer shell is usually a sealed glass tube, which contains two elastic iron plate electrodes and is also filled with inertia. Usually, the two Huang pieces made of materials in the glass tube are separated. When a magnetic substance approaches a glass tube, under the action of magnetic field lines, the two huang pieces inside the tube are magnetized and attracted to each other, and the huang pieces will be attracted together, making the circuit connected to the node connected. After the external magnetic force disappears, the two huang pieces separate due to their own elasticity, and the circuit is also disconnected. Therefore, as a circuit switching device that uses magnetic field signals to control, the dry huang tube can be used as a sensor for counting, limiting, and so on (mainly used in the production of door magnets and window magnets in security systems), and is also widely used in various communication equipment. In practical applications, Yongjiu magnets are usually used to control the connection of these two metal sheets, so they are also known as "magnetrons". A reed tube, also known as a magnetron, is similar to a Hall element, but its principle and properties are different. It is a type of switching element that uses magnetic field signals to control the circuit or mechanical movement. It has no magnetic disconnection and can be used to detect the state of the circuit or mechanical movement. Another type of magnetic switch is the proximity switch, door magnetic switch, or induction switch on the market. It has a well molded and large-sized plastic shell. The reed tube is sealed in a black shell, and the wire is led out. The other half of the plastic shell with a magnet is fixed at the other end. When the magnet approaches the switch with a wire, it sends a switch signal! The general signal distance is 10mm for connection, and this product is widely used in electronic equipment such as anti-theft doors, household doors, printers, telephones, etc. Another type of magnetic switch is to install one or more magnetic spring switches inside a closed metal or plastic tube, and then pass the tube through one or more hollow floating balls with ring shaped magnets inside. The fixed ring is used to control the floating balls and magnetic spring switches in the relevant positions, so that the floating balls float up and down within a certain range. Use the magnet inside the floating ball to attract the contact point of the magnetic spring switch, generating opening and closing actions.
