Magnetic Sensor from TDK Detects Microscopic Specks of Metal
nal-to-noise ratio in micromagnetic fields compared to Nivio, its
size is a mere 8 by 8 by 5 mm-small and thin enough to sit on a
fingertip. An xMR sensor is a magnetic sensor designed to measure
the strength of a magnetic field using magnetoresistance,
an effect where changes to electrical resistance occur depending
on the magnetic field.
Preventing contamination by microscopic debris is a vexing
matter for manufacturers of pharmaceuticals, cosmetics and
industrial chemicals. Even the tiniest speck of debris can trigger
serious consequences in our everyday lives. A microscopic
contaminant, for example, in the ingredients of a smartphone's
lithium-ion battery can cause capacity degradation, heat generation,
even ignition.
Attendees at Electronica 2022 held in November in Munich were
able to see a new solution for factories that have been utilizing a
plethora of inspection methods and sensors to remove miniscule
debris invisible to the human eye. TDK has newly developed a
highly sensitive, compact magnetic sensor capable of detecting
metal fragments smaller than 0.1 mm by applying spintronic
technologies it has amassed in the manufacturing of hard disk
drive heads.
The Migne xMR sensor is an xMR-type magnetic sensor based
on the company's Nivio magnetic sensor. With an improved sigFrom

In today's manufacturing environment, there is a growing demand
for the ability to detect iron and stainless steel particles
smaller than 200 µm (0.2 mm). Because non-magnetic metals
like aluminum and copper are viscous and tend not to become
fine particles, external contamination can be prevented by raising
the cleanliness of factories. Iron and stainless steel, however,
are difficult to eliminate as they are used as materials in
production equipment which inevitably generates fine particles.
Mainstream X-ray inspection is generally limited to several hundred
µm in detectable debris size, giving rise to a need for the
ability to detect smaller debris.
