MS2100 2-Axis Magnetic Sensor
Specifications and User Instructions
General Description
The MS2100 is an integrated surface mount
technology (SMT) module designed for 2-axis
magnetic field sensing. The MS2100 combines
PNI Corporation’s patented magneto-inductive
(MI)
sensors and measurement circuit
technology into a surface mount package for
unparalleled performance. The MI sensors
change inductance by 100% over their field
measurement range. This variable inductance
property is used in the cost and space efficient
MS2100,
which incorporates a patented
temperature, and noise stabilized oscillator/
counter circuit with a SPI interface. The
microprocessor-compatible SPI interface allows
easy access to the MS2100’s measurement
parameters and resulting field measurement
data. The module also includes pins to support
the connection of a third MI sensor axis for
higher performance applications.
Advantages include 3V operation for
compatibility with new systems, low power
consumption, small surface mount packaging,
large signal noise immunity under all conditions,
and a large dynamic range. Resolution and field
measurement range are software configurable
for a variety of applications. The measurement
is very stable over temperature and inherently
free from offset drift.
These advantages make PNI Corporation's
MS2100 the choice for high volume applications
where small size and low power requirements
are paramoun
t.
