About Comidox 214mm Glass Reed Switch Magnetic Sensor

Product description： Principle: Reed switch is a kind of contactless passive electronic switch element. Its shell is generally a sealed glass tube. The tube is equipped with two iron elastic reeds and it is also filled with a metal. Barium inert gas. At ordinary times, two reeds made of special material in the glass tube are separated. When there is a magnetic substance near the glass tube, the two reeds in the tube are magnetized and attracted to each other under the action of the magnetic force lines of the magnetic field, and the reeds are sucked together so that the circuit connected to the node is connected. After the external magnetic force disappeared, the two reeds were separated due to their own elasticity and the lines were disconnected. Therefore, as a line switching device controlled by a magnetic field signal, the reed switch can be used as a sensor for counting, limiting, etc. (in the security system, it is mainly used for making door magnets and window magnets). It is widely used in various communication devices. In practice, the permanent magnets are usually used to control whether the two metal plates are connected or not, so they are also called "magnetrons". Usage Instructions: Shear or bending pin must be extremely careful to avoid plaing undue strength to damage glass tube. Long time heated may damage the component, welding technology must be fast and reliable.
