NVE Corporation Introduces New Current-Over-Trace Sensor
EDEN PRAIRIE, Minn.January 31, 2018NVE Corporation today announced
the AAL024-10E analog magnetic field sensor. The new sensor combines small size,
high sensitivity, and cross-axis sensitivity for an ideal current-over-trace sensor.
The new sensor uses NVEs patented spintronic Giant Magnetoresistance (GMR)
materials. A Wheatstone bridge magnetometer configuration provides temperature
stability and cancels ambient magnetic fields.
High sensitivity provides 300 millivolts per amp typical levels with a five-volt
power supply. The sensor is inherently omnipolar for AC or DC measurements.
The AAL024-10E is precise and accurate. Key specifications include:
3.6 millivolts per volt per oersted typical magnetic sensitivity
1.5 to 10.5 oersted linear range
less than 4% nonlinearity
less than 2% hysteresis
The part is packaged in an ultraminiature 2.5 by 2.5 by 0.8 millimeter
Sensors are in stock for immediate delivery, and priced at $2.57 each in 1,000-piece
quantities. Datasheets and more information are available at www.nve.com.
An evaluation board, the AG903-01E,
is also available. The boards include four AAL024-10E current sensors on a circuit
board with four different current-trace configurations. These boards support noncontact
current measurement up to five amps AC or DC. The boards measure two by two inches
(50 by 50 millimeters), and include screw connections for 14 to 30 gauge wire
for the current to be measured. Evaluation boards are available now and priced
at $75 each.
NVE is a leader in the practical commercialization of spintronics, a nanotechnology
that relies on electron spin rather than electron charge to acquire, store and
transmit information. The company manufactures high-performance spintronic products
including sensors and couplers that are used to acquire and transmit data. NVE
has also licensed its spintronic magnetoresistive random access memory technology,
commonly known as MRAM.
