Available in hundreds of sizes and shapes, crucial in dozens of industries, and equipped to survive billions of operations in even the most extreme environments, the Reed Switch can outmatch and outlast many of its competitors. It continues to grow in popularity as the core component in relays and sensors for switching, detecting, and counting applications across the globe.
At its core is a glass-to-metal hermetic seal, which encloses the two ferromagnetic reeds in a glass envelope and protects them from the outside environment. As a result of this simple construction, the Reed Switch can operate in even the harshest conditions. In addition, it requires no direct contact when part of a reed sensor.
