NVE Introduces Tunneling Magnetoresistance Gear-Tooth Sensors

EDEN PRAIRIE, Minn.—August 30, 2021—NVE introduced the world’s first practical non-inductive gear-tooth sensors 25 years ago, and is revolutionizing the market again with the world’s first Tunneling Magnetoresistance (TMR) gear-tooth sensors.

NVE’s ABT-Series Gear-Tooth Sensors are versatile analog sensors, typically used with back-biasing magnets to encode the position of a ferrous gear:
 
ABT-Series Sensor Operation

The sensors have two channels to detect direction.

Key features include:
   • Angular resolution as fine as 0.001 degrees
   • Large analog peak-to-peak signals
   • Operating frequency to 350 kHz
   • 150 degrees Celsius operating temperature

Applications include:
   • Motion, speed, and position sensing
   • Linear and rotational encoders
   • Closed-loop servo systems
   • Machine tools
   • Automotive sensors

Multiple Options
Four ABT-Series models are available to match a wide range of gear pitches. All four are in stock for immediate delivery:
 
Part
    Number    
Gear Pitch
 Package 
ABT250-00E 0.6 to 2 millimeters MSOP8
ABT375-00E 1 to 3 millimeters
ABT500-00E 1.3 to 4 millimeters
  ABT600-00E     1.6 to 4.8 millimeters  

Demonstration Board
The AG972-07E Demonstration Board showcases rotational encoding to a few thousandths of a degree with an ABT375-00E sensor. The kit includes a circuit board, a sensor, an eight-digit rotational display, and a bias magnet. The demonstration is powered by two AAA batteries (included).
 
Available Now
The ABT250-00E, ABT375-00E, ABT500-00E, and ABT600-00E are available now for immediate delivery. The parts end-user price is $2.18 each in 1000-piece quantities, and distributor discounts are available. The AG972-07E Demonstration Board is also in stock for immediate delivery, with an end-user price of $195 and a distributor price of $146.25.
