KMZ41 - Magnetic field sensor

Datasheet Summary

Description

The KMZ41 is a sensitive magnetic field sensor, employing the magneto-resistive effect of thin film permalloy.

The sensor contains two galvanically separated Wheatstone bridges, which enclose an angle of 45 degrees.

Features

  • Accurate and reliable angle measurement.
  • Mechanical robustness, contactless principle.
  • Wear-free operation.
  • Accuracy independent of mechanical tolerances.
  • Extended temperature range 1.3 Quick reference data Table 1. Quick reference data Tamb = 25 °C and Hext = 100 kA/m, VCC = 5 V unless otherwise specified. Symbol Parameter Conditions Min Typ Max VCC supply voltage [1] - 5 9 Vpeak peak voltage see Figure 2 [1] 73 81 89 Voffset offset.

KMZ41 Magnetic field sensor Rev. 6 — 18 November 2010 Product data sheet 1. Product profile 1.1 General description The KMZ41 is a sensitive magnetic field sensor, employing the magneto-resistive effect of thin film permalloy. The sensor contains two galvanically separated Wheatstone bridges, which enclose an angle of 45 degrees. A rotating magnetic field strength > 40 kA/m (recommended field strength > 100 kA/m) in the surface parallel to the chip (x-y plane) will deliver two independent sinusoidal output signals, one following a cos(2α) and the second following a sin(2α) function. The sensor can be operated at any frequency between DC and 1 MHz. 1.
