A Reed Sensor is a small device that consists of two metal contacts encased in a glass tube. When a magnetic field is applied, the contacts come together and complete an electrical circuit. This change in circuit can be used to detect the presence or absence of a magnetic field.

Reed sensors have many applications, such as in security systems to detect open or closed doors or windows. They are also used in automotive applications, such as determining if a door is open or closed. In addition, reed sensors are used in industrial settings, like detecting the presence or position of objects.

Some applications with vibration or shock may need to use a higher AT band and a stronger magnet and some applications need a wider actuating distance that can only be achieved with a smaller AT band. For the right selection of reed sensor and actuating magnet, we have provided information on the combination of magnet and AT bands to select for an application requirement. Some applications require only an actuating distance and some critical ones may need an actuation and a lreeasing distance.

Although some of the AT band / magnet combinations will produce similar actuating distances, selecting the right AT band and magnet for an application is important and can be done by going through our AT band Selection guide and our magnet selection guide. Please contact us for more information.

In conclusion, this page lists various combinations of Reed Sensor AT bands and magnet combinations that help users select the right combination for their applications.
