Axes of Sensitivity

TMAG5110 and TMAG5111 each offer all possible combinations of two axes. That is XY, ZY, and ZX. Each combination is available as a different package variant within the same product family. The polarity which is best for a given application will vary based on how the sensor is to be aligned with the magnet. These devices offer flexibility to use a surface mount package without the need for additional PCBs or devices that require significant vertical space. The following sections show some possible configurations.
