The proximity interview of the reed switch offers some advantages which make it a part and parcel in modern technology. To begin with, the reed contacts never actually touch each other so there is no wear out. So, in other words that equates to like almost an endless life time and reliability. Moreover, it can feel changes in magnetic fields quickly due to fast response times so they should be used whenever you need the fastest approaching sensor. Thirdly, and no moving parts equates to next too zero mechanical failures in the design of these units when they are maintained as required maintenance costs will be minimized. In addition to that, it is versatile as its small footprint makes this equipment easier for being combined with superior devices. And if something went wrong, it should still not only feel great and operate but look great too! Last but definitely not least, this switch is extremely resistant to environmental contaminants. We have always seen it perform, and it performs well — not just good — in non-polluted conditions. For integrators using these components, it will net lower costs in money and energy savings by default (though the very low-cost nature of deployment mean margins remain thin or non-existent), across-the-system performance increases for whole systems, thus improved user-experience.
