Sensor Product Selector Guide
AA and AB-Series analog GMR sensors have high sensitivity, excellent temperature
stability, low power consumption, and small size.
GMR Switches integrate GMR sensor elements with digital onboard signal processing
electronics. NVE offers three series of GMR Switch Precision Digital Sensors:
Digital Sensors with a 4.5 V 30 V supply voltage
bipolar (south field ON, north field OFF) digital sensors
digital sensors with supply voltages as low as 0.9 V
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.
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.
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.
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.
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
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..
