Reed sensors use a magnet or electromagnet to create a magnetic field that opens or closes a reed switch within the sensor. This deceptively simple device reliably controls circuits in a wide range of industrial and commercial goods. In this article, we’ll discuss how reed sensors operate, the different types available, the differences between Hall…Read More
Reed switches and Hall Effect switches are both considered magnetic switches since their properties change when exposed to a magnetic field. Strictly speaking, however, Hall Effect switches are transducers since they convert magnetic energy to electrical energy—they can be used as switches with some additional circuitry. Reed switches are true magnetic switches since they close…Read More
If you’ve ever used a laptop or a flip phone, you may have wondered how the screen goes dormant once you close the device. Or maybe you’re curious about why your tablet screen turns on every time you open its protective cover. At the heart of these functions is an ingenious device called a reed…Read More
