Magnetic Induction Sensor
Magnetic Induction Sensor's main component of the material comes from the reed switch. A reed switch is a magnetically sensitive special switch. It usually consists of two or three both magnetically conductive and conductive materials made of reed contacts, is encapsulated in an inert gas-filled (such as nitrogen, helium, etc.) or vacuum glass tube, glass tube inside the tube parallel encapsulated reed end overlap, and leave a certain gap or contact each other in order to constitute a switch normally open or normally closed contacts.
