NVE Corporation Product Announcement
NVE Introduces Its Most Sensitive Sensor Ever

EDEN PRAIRIE, Minn.—December 20, 2021—NVE has introduced its most sensitive magnetometer sensor ever.

The new ALT023 is a version of the popular ALT025 Tunneling Magnetoresistance (TMR) analog magnetometer with ten times the sensitivity. The ALT023 uses NVE’s revolutionary TMR technology to precisely measure fields from a few microtesla to 1 millitesla.

The differential bridge outputs are bipolar, meaning positive for a positive field and negative for an opposite field polarity.
 
Key ALT023 specifications include:
  • High sensitivity (200 mV/V typical full-scale)
  • Flexible 0 to 5.5 V supply (no minimum)
  • 20 kiloohm device resistance for low power
  • mT linear range
  • High linearity (<1 % of full-scale)
  • Ultra-low output temperature coefficient (<0.1%/°C)
  • Up to 300 kHz bandwidth
  • -40 to 125 °C operating range
  • 2.5 by 2.5 mm TDFN6 package

Applications include non-contact current sensing; motion, speed, and position control; mechatronics and robotics; and geomagnetic navigation.

There are currently two ALT-Series TMR Magnetometer versions:
 
Part
    Number    
Linear Range
    Sensitivity   
ALT023-10E 0 to 1 mT 200 mV/V/mT
ALT025-00E 0 to 10 mT 20 mV/V/mT
 
The ALT023-10E and ALT025-10E are both available now for immediate delivery. The parts end-user price is $5.68 each in 1000-piece quantities.
