Position sensors are sensors, which measure
linear or angular position.
Following the trend towards robust and
intelligent sensor systems and applications
ams offers a broad portfolio of non-contacting
(without physical contact), hall-based and
intelligent magnetic position sensors with high
reliability and long functional life.
With these position sensor solutions we are
serving high-growth applications within the
automotive (safety critical automotive
applications concerning transmission, pedal,
steering, chassis), consumer (home
appliances), industrial (manufacturing, building
and office automation, medical) and robotics
markets.

We offer our customers and potential customers
more than just a product.
Our value proposition supports high-performance,
superior durability, adherence to the most stringent
safety requirements, and best-in class stray field
immunity.
Based on our differential principle (patented
technology) all ams magnetic position sensors can
withstand external magnetic stray fields above the
limits required by the most demanding OEM’s.
This is growing increasingly in importance,
especially in the automotive arena as the drivetrain
of vehicles becomes partially or wholly electrified,
the environment becomes more electromagnetically
and mechanically harsh, and new standards such
as ISO11452-8 (immunity to magnetic fields) and
ISO26262 (functional safety) become adopted.

Rotary and linear magnetic sensor technology
shows robust growth, and particular trends in
the automotive industry.
The need for contactless technologies
(increased need for precision & safety),
improvements in reliability & precision, lower
CO2 emissions requirements, cost reduction,
and the increased use of brush-less (BLDC)
motors favors ams.
Therefore we are encouraged to put significant
weight behind magnetic position sensors for
applications in automotive systems

Sensors which measure linear or angular position
• Contacting: through a mechanical connection
• Non-contacting: without physical contact
Non-contacting position sensors are
• More reliable
• Offer a longer functional life due to the absence of
mechanical parts and physical contact
Strong trend
• From simple angle and distance sensors towards robust,
intelligent sensor systems and applications with multiple
simultaneous measurement axes.

The need for contactless technologies
• Increased need for precision & safety (i.e. ISO26262)
Improvements in reliability & precision
• More electronics in the car, higher precision in powertrain
applications e. g. start/stop systems, powertrain hybridization,
Lower CO2 emissions requirements
• Better sensor performance & higher resolution, e.g. steering
applications with reduced standby current and a smart
“measurement on demand”
Cost reduction
• Sensors with new digital interfaces i.e. SENT, PSI5 with
enhanced robustness/diagnostic, cost reductions for the entire
signal chain
Increased use of brush-less (BLDC) motors
• Major advantages of brushless DC motors include higher
efficiency at converting electricity into mechanical power,
reduced noise, longer lifetime and higher reliability.

Normal operation
Hall-based magnetic position sensors
(1) The magnet is centered over the Hall sensors (2) The magnetic field is sinusoidal, the magnetic
field strength increases linearly with radius
=> 1 turn = 1 sine wave
(3) The differential amplifiers generate one sine
and cosine signal with double amplitude
(4) The Cordic transforms sine and cosine into
angle and magnitude
