Noncontact Angle Sensors
AAT-Series
high-output, noncontact angle sensors measure rotating magnetic fields. Typical
applications include rotary encoders and motor shaft position sensors.
AAT-Series Sensor outputs are proportional to the supply voltage and peak-to-peak
output voltages are much larger than other sensor technologies.
Key features include:
• Tunneling Magnetoresistance (TMR) technology
• High bridge resistance for low power
• Large output signal without amplification
• Wide airgap tolerance
• Sine and cosine outputs for direction detection
• 0.5 degrees maximum angular measurement error
• Ultraminiature 2.5 mm x 2.5 mm x 0.8 mm
