The Magnetic Reed Switch LS-311-B31 is with permanent magnet and can be used for door and windows, It is easy to be mounted on the surface. When the detector is working, the permanent magnet make the contacts of the reed switch connectivity, and output switch signals for the alarm system (passage alarm, open circuit alarm). The detector should be used according to the material of the door/window, installation method and
movement distance.

NC–When the magnet need the switch, reed switch is closed, the signal line is connecte. If the door is opened, the magnet left switch, reed contact is disconnected, the signal line is interrupt, known as “circuit alarm”.NO–NC & NO–Convertion output optional The resistance will increase as the wiring get longer
