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:


The sensors have two channels to detect direction.

Key features include:
• 0.001° resolution
• Large analog peak-to-peak signals
• Operating frequency to 350 kHz
• 150 °C 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:


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 eigh-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.
