PORTFOLIO
The 2SS52M Series is part of Honeywell’s family of Digital
Magnetoresistive Sensor ICs:
• SM351LT, SM353LT
• SM351RT, SM353RT, SM451R, SM453R
DESCRIPTION
The 2SS52M Series Digital Magnetoresistive Sensors are
omnipolar, solid-state sensors with 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 in response to very low magnetic
fields.
These sensor ICs may be operated with either a North or a
South magnetic pole applied in parallel to the sensor IC. The
polarity does not need to be identified, simplifying installation in
single pole applications and doubling the resolution in rotating
magnet applications.
These small and highly sensitive omnipolar devices have
become a popular building block for flow metering, motor RPM
and cylinder position sensing.
They are available in five package styles:
•
2SS52M:
U-pack, 3-pin, in-line sensor IC with straight leads
supplied in bulk packaging (1000 units per bag)
•
SS552MT:
SOT-89B surface-mount sensor IC supplied on
tape and reel which allows for compact design with automated
component placement (1000 units per tape and reel)
•
2SS52M-S:
U-pack, 3-pin in-line, surface-mount sensor IC
supplied in bulk packaging (1000 units per bag)
•
2SS52M-T2:

leads supplied in ammo pack tape-in-box (5000 units per box)
•
2SS52M-T3:
U-pack, 3-pin, in-line sensor IC with straight
leads supplied in ammo pack tape-in-box (5000 units per box)

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