Although reed switch applications are immense, we have broadly classified them into the five categories. These are not to be construed by any means as a guideline, but most applications do fall under one of these types.

Position Sensing applications are generally used to sense a single operate or a release, and pulse counting applications are used where multiple high speed sensing is required. Relay applications sense external electromagnetic fields and Temperature sensing applications make use of diamagnetic alloys. The posts below describe more about how these types of applications work and also offer simple guidelines to selecting the right products and specifications.

In the actual application pages, we have also suggested recommended products for each category, but this does not mean that other products will be unsuitable. The usage of reed switches and reed sensors is fairly straightforward and simple, provided certain guidelines and precautions listed in our usage notes, Magnet selection guide, and recommended Contact protection are followed.
