Electrifying News From NVE

Over-Trace High Current Sensing

Eden Prairie, Minnesota - October 31, 2018 - NVE Corporation, a leader in the practicial commercialization of spintronics, has a new demo board can measure up to 40 amps through a circuit board trace using a noncontact GMR sensor!

The sensors detect the magnetic field generated by the current through a heavy-duty trace.

The board measures 2.5 by 2.75 inches (64 by 70 mm). The three modules are optimized to measure currents of 0 to 1 amp, 0 to 5 amps, and 0 to 40 amps. Each module has its own screw connections and the modules can be snapped apart.

Unlike conventional current shunts, over-trace current sensing has no insertion losses, and GMR sensors have large signals and inherent electrical isolation.

Ultra-fast Magnetometers

NVE’s groundbreaking AAL-Series GMR analog magnetic sensors are now five times as fast. An new fabrication process increased the sensor bandwidth from an already darn fast 100 kHz to a ridiculously fast 500 kHz.

AAL-Series sensors are ideal for current sensing, and the new parts allow lightning-fast overcurrent protection and high-frequency sensing in state-of-the-art power conversion and motor control applications.

Key AAL-Series features include:
• Wheatstone bridge analog output
• 500 kHz frequency bandwidth
• Up to 3.6 mV/V/Oe sensitivity
• Omnipolar for AC or DC measurements
• <2% hysteresis
• Ultraminiature 2.5 mm x 2.5 mm x 0.8 mm TDFN6 available
