This Usage Notes section helps in the highlighting the various process steps that Reed Switches go through and how to handle them as safe as possible so that there is minimal damage or AT shift. Reed Switches, Reed Sensors and Magnet Sensors may need to be mounted suitably on various different types of PCBs, both SMT and on through hole types, and also be screwed on to enclosures after cable soldering. At times, even usage in custom plastic housings may need to be encapsulated. This would mean that various processes such as careful cropping of leads, soldering or welding, encapsulation in custom housings may required. As reed switches are delicate devices, it is recommended to follow certain precautions, for the storage and handling of Reed Switches and Magnets as well some usage notes to follow when taking up such processes.
