Actuation Distances for MS-105 Reed Sensors

by webmaster

Operate and release distances for the MS-105 reed sensor in the three standard AT bands when actuated with standard magnets are listed 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.
