Operate and release distances for the MS-104 ultra-miniature reed sensor in the two standard AT bands when actuated with standard magnets are listed below. All distances given are in mm, with tolerances of ±0.5mm. 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 FAQ and our magnet selection guide.
