Introducing the new ACT001-10E TMR Isolated Current Sensor from NVE. This is a high-sensitivity, inline analog TMR current sensor for AC or DC measurements.

The ACT001-10E is an ideal replacement for the recently discontinued NVE AAV003-10E GMR current censor.

The part is in an ultraminiature 2.5 x 2.5 mm DFN6 package with an integrated current strap. A Wheatstone bridge configuration provides a bipolar differential output proportional to the current through the strap

Key ACT001-10E specifications include:
