Product specification

KMZ10A1

DESCRIPTION

The KMZ10A1 is an extremely sensitive magnetic field

sensor, employing the magnetoresistive effect of thin-film

permalloy. Its properties enable this sensor to be used in a

wide range of applications such as navigation, current and

earth magnetic field measurement etc. The special

arrangement of the sensing chip allows the construction of

coils for switching the auxiliary field (Hx) along the length

axis of the sensor. The sensor can be operated at any

frequency between DC and 1 MHz.
