proximity reed switch
The reed switch is a clever invention which can detect the presence or absence of a magnetic field at a distance. It comprises two thin ferromagnetic reeds enclosed in a glass tube, which is shut electrically when it is influenced by a magnetic field. Its major functions include sensing, a physical contact and security. These are required by many industries. In terms of technology, the proximity reed switch features non-contact operation, lightning response times and the highest durability. These switches are used in many fields as automotive, aerospace, consumer electronics and medical devices where they provide accurate control ranging from manual control, to automated control.
