KMZ11B1

The leadframe material is a copper alloy containing 2% iron. In applications with magnetic fields outside the specified operating range an increasing hysteresis effect will arise due to magnetization effects in the leadframe. However, in angular measurement applications of the KMZ11B1 in combination with strong magnetic fields H > 50 kA/m there is no additional hysteresis present.

The KMZ11B1 is a 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 for current and field measurement, revolution counters, angular or linear displacement sensors, proximity detectors, etc.  The sensor can be operated at any frequency between DC and 1 MHz.
