Various types reed switch is an electrical switch operated by an applied magnetic field. It consists of a pair of contacts on ferromagnetic metal reeds in a hermetically sealed glass envelope. The contacts may be normally open, closing when a magnetic field is present, or normally closed and opening when a magnetic field is applied. The switch may be actuated by a coil, making a reed relay,or by bringing a magnet near to the switch. Once the magnet is pulled away from the switch, the reed switch will go back to its original position.
Usage: speed sensor
Theory: current sensor
Output: analog sensor
Reed switch: magnetic reed switch
Reed switch price: magnetic contact reed switch
SMD reed switch: magnetic reed switch sensor
Reed switch 50W: wireless reed switch
An example of a reed switch’s application is to detect the opening of a door, when used as a proximity switch for a burglar alarm.
1.Reed contacts are hermetically sealed within a glass tube and do not receive the external atmospheric environment.
2.Quick response,and light weight.
3.Superior corrosion resistance and wear resistance of the contacts assures stable switching operation and long life.
4.Composed fast with the coil and magnet,reed switch can be used for reed relay or sensor.
5.Widely used in household appliances,control equipment,communication equipment,automotive electronic devides,warning devices,and measurement equipment,etc.
