FH3D02 Overview

1.1

General Description

The FH3D02 is a dual 3D magnetic field sensor using two 3D Hall sensors using the HallinOne

technology, which are also called “pixels”. The versatile magnetic field sensor is suited for measuring all

magnetic field components in three dimensions. It can be used as a magnetic field probe or a position

sensor for linear or rotary movement of permanent magnets. A variety of applications can be evaluated

instantly with the standard programming. With specific programming even more applications can be

addressed.
