GUC80 Magnetic Intrinsic Safety Explosion proof Magnetic Proximity Switch Product Introduction: A magnetic switch, as the name suggests, is a switch that is induced by a magnet. Magnetic switches are used to detect the position of the cylinder piston, that is, to detect the movement stroke of the piston. They can be divided into two types: contact type and contactless type. 1: Non contact type NPN2: Non contact type PNP3: Non contact anti magnetic type. Detailed explanation: Magnetic switch means induction through a magnet, which is a magnet. There are several types of magnets available in the market, including rubber magnets, permanent magnet ferrite, sintered neodymium iron boron, etc. 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".
