Honeywell introduces the latest generation of highly sensitive magnetic field sensors. The magnetic field sensors of the new Nanopower series work according to the magneto-resistive principle and offer the developers a high magnetic sensitivity with power consumption in nano-ampere range as well as high flexibility for design by means of a sub-miniature SOT-23 casing.
In addition, by using the sensors, savings can be achieved with a number of advantages. Thus, due to the high magnetic sensitivity of the sensors, low-cost magnets can be built in the application without having to accept losses in the measurement. Apart from that, the sensors of the series are omnipolar, which is why the orientation of the magnets need not be taken into consideration during the production process.
All sensors of the nanopower series listed so far require a supply voltage from 1.65 V to 5.5 V and work in a temperature range of -40°C to 85°C. As the name already suggests, the current consumption of these magnetic field sensors lies in the nano range, precisely at 310 nA or 360 nA depending on the sensitivity. So far there are two listings with different sensitivity levels: 7 Gauss type (max. 11 Gauss) and 14 Gauss type (max. 20 Gauss).
