Actuation Distances
Operate and release distances for the MS-104 reed sensor in the three standard AT bands when actuated (as shown in the
sketches) with NdFeB standard magnets is shown below. All distances given are in mm with tolerances of ±0.5mm. Distances
given will vary if the reed sensor leads are cropped after soldering. 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.
