TXC launches anti-magnetic hysteresis 3-axis electronic compass in 1.6mm x 1.6mm x 1.0mm plastic package. PM131 utilizes Anisotropic Magnetoresistance (AMR) Technology and provides anti-magnetic hysteresis, low power consumption and high Output Data Rate (ODR) advantage which prevails other branded products. Our product can automatically conduct calibration after getting outside magnetic interference. TXC will further develop 6-axis electronic compass products based on our state-of-art technology.
Major target applications are: Digital Compass, Virtual Reality, GPS and Pedestrian Navigation.
