The medical industry demands durable and efficient components that can work for millions of operations without degradation. High reliability Reed Sensors and Reed Sensors are used in applications such as Pace-makers and Neuro-stimulators. The same components are also used in non-critical devices such as hearing aids and pill-cams, and also in diagnostics equipments such as in scanners and X-ray machines. Highly reliable devices are required in the medical industry to ensure a long field life and ultra-miniature reed sensors perform excellently in lower power circuits. An added advantage in Reed Sensors is that they can work without drawing power for operation, which make them especially useful in battery connected devices. As applications in the medical industry are cropping up quite fast, we list how reed switches and reed sensors find themselves in the most widely used areas. We have suggested recommended products for use in each application, but this does not mean that the other products in the same product category will be unsuitable. We have also classified individual applications into types and these guidelines will help select the right magnetic sensitivity and type of magnet to use from our range of products.
