POTENTIAL APPLICATIONS
Industrial
• High frequency flow sensing in HVAC, water, fuel meters, and
gas utility meters
• Anti-tamper detection in water, electric, and gas utility meters
• Liquid level detection
• Motor RPM sensing
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.
• In-cylinder position sensing
Medical
• RPM sensing in exercise and rehabilitation equipment
• Magnetic interrupt in exercise and rehabilitation equipment
• Absence/presence detection in infusion pumps
• Position sensing of medication dispensing cabinet drawers
• Incline position sensing in hospital beds
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.
White goods
• Lid, door and drawer position detection
• Fluid flow detection
These small and highly sensitive omnipolar devices have
become a popular building block for flow metering, motor RPM
and cylinder position sensing.
• Liquid level detection
