Actuation Distances
Release, operate and re-closure distances for the R2B-S normally closed SMD 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. 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.
