NXP Semiconductors KMZ49
The KMZ49 is a sensitive magnetic field sensor, employing the magnetoresistive effect of thin-film permalloy. The sensor contains two galvanic separated Wheatstone bridges, at a relative angle of 45 to each other. The KMZ49 is suited to high precision angle measurement applications under low field conditions (saturation field strength 25 kA/m).| Part No. | KMZ49 |
