Product Description

The SS351AT, SS451A, and SS551AT sensor ICs are small and digital Hall-effect devices operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to either a North pole or a South pole. These products have a typical operating point of 85 G at 25 °C [77 °F]. Because they can be operated by a North pole or a South pole, they do not require the magnet polarity to be identified, thus making the installation easier and potentially reducing the system cost. These omnipolar sensors are sensitive and flexible devices designed to meet a wide range of potential applications.
 

These products are available in three package styles:

• SS351AT: Subminiature SOT-23 surface-mount package supplied on tape and reel which allows for compact design with automated component placement.

• SS451A: Flat TO-92-style package with straight leads in bulk packaging which allows for a compact PC board layout.

• SS551AT: SOT-89B surface-mount package on tape and reel.

FEATURES

• Simple activation from a North pole or a South pole and sensitive magnetics

• Low voltage 3 Vdc capability

• Built-in reverse polarity protection

• Thermally balanced integrated circuit

• RoHS-compliant materials meet Directive 2002/95/EC

POTENTIAL APPLICATIONS Commercial

• Speed and RPM (revolutions per minute) sensing in fitness equipment

• Magnetic encoder for building access

• Damper or valve position control in HVAC (heating, ventilation, and air conditioning) equipment

• Flow-rate sensing in appliances and water softeners

• Printer head position sensing

Industrial

• Flow meters

• Robotic control (cylinder position monitoring)

• Float-based fluid level sensing

• Motion control

• Proximity sensing

• Instrumentation

• Metering

Medical

• Position sensor in hospital beds and medical equipment

• Medication bin monitor on portable drug carts

PORTFOLIO
