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.
