NVE has recently introduced its most sensitive magnetometer sensor to date.
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, 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, and up to 300 kHz bandwidth. 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.
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. For more info, visit www.nve.com .
