High sensitivity sensors withstand shocks from dropping without risk of severe damage

Reed switches appear to be an attractive solution when it comes to battery-operated devices essentially because they are cheap, don't require power and therefore simplify customers design. Reed switch OEMs themselves highlight the numerous precautions that are required when handling reed switches, resulting in a higher cost of ownership for customers (including warranty costs). Unlike reed switches, Honeywell MR sensors, available from TTI Europe, withstand shocks and vibrations better and may be dropped without the risk of severe damage. No need to cut and bend leads on an MR SOT-23 sensor and, therefore, no risk of altering the component characteristics. Soldering an MR sensor does not require special preheating to prevent heat stress damage. Any ultrasonic welding, sealing or cleaning process will not affect the MR sensor. Therefore, no additional exhaustive testing would be required. Mounting a reed switch on a PCB often requires manual operations to either elevate the reed switch above the board using an additional holder or to drill a hole in the board to avoid direct contact with the board, when surface mount SOT-23 components are designed for automatic insertion on a PCB. Using an MR solution not only saves on costs for OEMs, but also brings comfort of use and long-term reliability and durability for the end users.
