General Description

This device is a special tangential field difference sensor with two AMR (Anisotropic Magneto-Resistive) bridges for field movement measurements or field comparative measurements.

The ZMX40M contains two extremely sensitive magnetic sensor chips, mounted parallel to each other in an SM8 package, employing the magneto-resistive effect of thin film permalloy.

It allows the measurement of magnetic fields or the detection of magnetic parts.

Overview

DUAL MAGNETIC FIELD SENSOR ZMX40M.

Key Features

Output voltage proportional to magnetic field Hy across each chip.
Both chips are in the same orientation and chip centres are 3mm apart in Y direction.
Magnetic fields vertical to the chip level Hz are not effective.
Disturbing fields Hx up to 30 kA/m are allowed.
Extremely small chip distance from the top side of package for accurate measurement When the two peaks are the same amplitude, the magnet must be mid-way between the two chips. Therefore.
