Actuation Distances for R5 Ultra-miniature Reed Sensors

Operate and release distances for the R5 ultra-miniature reed sensor in the two lead formations and 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.
