R2-S SMD Reed Sensor

Actuation Distances

Operate and release distances for the R2-S ultra-miniature reed sensor in two 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.
