In summary, Honeywell’s Nanopower series of magnetoresistive sensor ICs, consists of the SM351LT and SM353LT, offering design engineers high magnetic sensitivity, Nanopower consumption, design flexibility, and savings due to the ability to use low-cost magnets. These sensors offer features including two magnetic sensitivities, nanopower consumption which enable the devices to be used in battery operated equipment, a supply voltage range of 1.65 V to 5.5 V, a temperature range of -40°C to 85°C, and the use of RoHS-compliant materials. Some advantages of the Nanopower series are the magnetoresistive sensor senses in the parallel plane and has a higher level of sensitivity compared to a Hall-effect sensor, and lower power consumption compared to competitive MR sensors. Honeywell's SM353LT and SM351LT have equal to or better sensitivity than competitive MR sensors, making them a great choice when an application requires low power and high sensitivity. Additionally, the SM351LT can replace reed switches with the addition of very little power. They are more reliable and stable over the temperature range, do not wear out over time, and have a higher quality and durability. Plus, unlike the glass reed switch, the plastic molded MR sensor does not break.
