NVE's AKL003-12E GMR GMR Gear Tooth Sensor is a digital output speed sensor for coarse-pitch gear tooth sensing and magnetic encoders. It is based on NVE's ABL006 differential sensor, and is easily biased with a permanent magnet for use with a gear-tooth style target. It provides a large airgap and 50% duty cycle current-modulated output over the -40C to +150C temperature range.
This is a Lead (Pb) free, RoHS compliant part.
