Magnetoresistive Position Sensors
SS552MT Surface Mount Sensor
SS552MT Series
FEATURES
• Low gauss operation can
extend sensing distance to
one inch or more,
depending upon size
• Digital current sinking
output
• Omnipolar – can be
operated with either north
or south magnetic pole
SS552MT is a digital position sensor in an SOT-89 style surface-mount
package with omnipolar magnetic action. The sensor has magnetoresistive
material integrated on silicon and encapsulated in a plastic package. The
integrated circuit provides a digital output in response to very low magnetic
fields. Though this signal is identical to our digital Hall effect sensors, it can
be achieved by magneto-resistive sensors at much greater sensor-to-
magnet distances.
• 0 kHz to over 100 kHz
operating speed
• Surface-mount package
allows automated, lower
cost assembly
• Small size
Surface-mount packages are mounted directly on the electrical traces on the
PC board and attached by an automatic solder reflow operation which
requires no holes, so it reduces the cost of the PC board. These packages
are supplied on tape and reel and can be automatically placed on PC boards
by use of pick-and-place equipment.
TYPICAL APPLICATIONS
• Cylinder position sensing
in pneumatic cylinders
• Elevator sensor
• Lid sensor for laptop
computers
SS552MT Series is operated by magnetic fields (North or South) parallel to
the sensor package.
• Position sensor for material
handling equipment
• Geartooth sensor for
industrial or automotive
applications
NOTE: Due to the inherent high sensitivity of these sensors, stray magnetic
fields which are parallel to the IC may affect operation.

*Absolute maximum ratings are the extreme limits
the device will withstand without damage to the
device. However, the electrical and mechanical
characteristics are not guaranteed as the maximum
limits (above recommended operating conditions) are
approached, nor will the device necessarily operate
at absolute maximum ratings.
