Weakfield sensors
Maximum sensitivity while minimizing temperature influences
NXP's KMZ10 family and KMZ51/52 magnetoresistive sensors are ideal for applications requiring the sensing of weak magnetic fields, like that of the Earth. Consisting of four magnetically sensitive permalloy resistors arranged in a Wheatstone bridge configuration, maximizing sensitivity while minimizing temperature influences.
Key benefits
- High sensitivity and reliability
- Wear-free operation
- Built-in compensation coils
- Wide frequency range
- High operating temperatures
Descriptive summary
The sensors offer all the inherent advantages of magnetoresistive technology, with none of the trade-offs between precision and sensitivity, frequency limitations, temperature restrictions and other drawbacks found with many other sensing techniques. The KMZ51/52 have built-in coils for individual offset compensation. Many applications require a two-sensor element, so our KMZ52 also integrates two-coordinate measurement in one package, reducing design-in effort even further.
