Analog Sensors
AA and AB-Series analog GMR sensors have high sensitivity, excellent temperature stability, low power consumption, and small size.

Digital Sensors
GMR Switches integrate GMR sensor elements with digital onboard signal processing electronics. NVE offers three series of GMR Switch Precision Digital Sensors:
  • AD-Series Digital Sensors with a 4.5 V – 30 V supply voltage
  • ADV001-Series bipolar (south field ON, north field OFF) digital sensors
  • AFL-Series digital sensors with supply voltages as low as 0.9 V

Current Sensors
AAV003-10E current sensors are highly linear, extremely low hysteresis GMR current sensors with on-chip current straps. GMR bridge sensor elements close to the straps sense the current. The output of the bridge voltages are bipolar and proportional to the current through the strap over a -80 to +80 mA input range.

Medical Sensors
NVE spintronic GMR sensors are proven solid-state components with no moving parts for inherent reliability, as small as 1 sq. mm or less, sensitive to fields as low as 1 Oe (0.1 mT), and with very low power consumption. Applications include reed switch replacement, hearing aids, pacemakers and ICDs, neurostimulators, and insulin pumps. Products include Wheatstone bridge output and digital switches with integrated comparator.

GT Sensors™ Precision Gear Tooth and Encoder Sensors
GT Sensor™ sensors are designed for detection of gear teeth and magnetic encoder wheels in industrial speed sensing. Dual-output versions are available with the second output phase shifted with respect to the first for quadrature to determine direction. Low profile MSOP8, TDFN SO8, and TDFN6 packages allow GT Sensors to fit in the tightest spaces.
NEW! Angle Sensors
AAT-Series angle sensors use Tunneling Magnetoresistance (TMR) technology to produce a very high output signal without amplification, anda wide airgap tolerance. Sine and cosine outputs provide full quadrature. TDFN6 packages. The AAT001 has high resistance for extremely low power; the AAT003 is lower resistance for simple interface.

Peripheral ICs
NVE provides unique ICs for use with its own or other sensors.

DB-Series interface ICs are designed for industrial control applications requiring a digital current output of up to 200 mA; DC-Series voltage regulators for high voltage, low current applications; and DD-Series Signal Processing ICs, designed to complement ABL-Series GT Sensors to provide a current-modulated digital output.

Evaluation Kits
NVE offers several evaluation kits at nominal cost so customers can try its remarkable sensors in their application. Available kits include the AG001-01 Analog Sensor evaluation kit, the AG003-01 current sensor evaluation kit, the AG910-07 and AG911-07 GMR Switch evaluation kits, the AG920-07 GT Sensor evaluation kit, and the AG930-07 Angle Sensor evaluation kit.
NVE offers several popular permanent magnets for use with magnetic sensors..
