Solid State Sensors
Digital Magnetoresistive Sensor
2SS52M Series
HONEYWELL Sensing and Control
FEATURES/BENEFITS
Advanced electronic circuitry
including a band-gap
regulator. Can be used with
a wide range of supply
voltages.
Low gauss operation can
extend sensing distance to
one inch or more, depending
on magnet size.
Digital current sinking output
Omnipolar - can be operated
with either North or South
magnetic pole. Will simplify
installation in single pole
applications and double the
resolution in rotating magnet
applications.
Operating speed: 0 to over
100kHz; will keep up with
fast moving targets.
3-pin, in-line PC board
terminals on 0.050-inch
mounting centers (0.100
centers available on tape for
automated assembly).
Operating temperature
range: -40° to +150°C (-40°
to 302°F) allows use in
extreme temperature
conditions.
Surface mount style
available 2SS52M-S for
mounting flexibility.
TYPICAL APPLICATIONS
Cylinder position sensing
Elevator sensor
Laptop lid sensor
Geartooth sensor
Blood analyzer
Industrial proximity sensor
High-resolution magnetic
encoder
2SS52M Series position sensors have a built-in magnetoresistive bridge
integrated on silicon and encapsulated in a plastic package. The integrated
circuit also includes a band-gap regulator and a digital output that will
respond to very low magnetic fields. Though the signal is identical to our
digital Hall effect sensors, it can be achieved by magnetoresistive sensors
at much greater sensor-to-magnet distances.

OPERATING MODE (Arrows indicate direction of magnetic flux.)
2SS52M sensors are operated by magnetic
fields (North or South pole) parallel to the
magnetoresistive element.
Note: Due to the inherent high sensitivity of
2SS52M sensors, stray magnetic fields that
are parallel to the IC may effect operation.
