Actuation Distances
Operate and release distances for the MS-324 miniature Flat pack sensor in 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. 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.
