Reed Switch Magnet Interaction Slide 25

In summary, knowing the details behind how reed switch sensors work can offer much insight into their proper operation. Reed switch sensors are comprised of a reed switch and a magnet. Reed switches are packaged appropriately for their application. The magnet is usually attached to a moving mechanism that allows the magnet to be brought into the reed switch’s sphere of influence. Here the magnetic flux interacts with the sensitivity lobe arrays creating the switching function. Understanding their influence with each other is key to a successful reed sensor application.
