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 stated in these usage notes, for the storage and handling of Reed Switches and Magnets as well some usage notes to follow when taking up such processes.

One important consideration when using reed switches or reed sensors is the selection of ampere-turns or magnetic sensitivity. Temperature also plays a significant role in the performance of reed sensors. It is important to note that reed switches have certain temperature limits, and exceeding these limits can lead to operate instability or even permanent damage. Therefore, it is important to consider the effects of temperature and ensure the sensors are used within their specified temperature range as specified in these usage notes.

During the assembly process, reflow soldering is commonly used. Reed sensors are sensitive devices, and excessive heat during the soldering process can damage them. Therefore, it is important to follow proper reflow soldering techniques as specified in these usage notes, to avoid any damage or performance issues. Additionally, understanding the effects of magnets on reed sensors is essential. It is important to carefully select and position magnets to ensure proper functioning of the reed sensors.

In conclusion, proper understanding and utilisation of reed sensors and their related considerations are crucial for achieving optimal performance and reliability in various applications.
