OverviewPerformance ParametersApplication

GC-CC-302A High-precision Micro-magnetic Basic Sensor is a sensor that is based on the Giant Magneto Impedance (GMI) effect and characterized by axial acquisition. With a special signal processing circuit, it achieves high detection sensitivity, which can reach 20pT in a relatively stable environmental magnetic field. The micro-magnetic sensor can be widely used in fields such as magnetic anomaly detection, high-precision magnetic measurement and scientific research with high requirements for magnetic field detection sensitivity. Compared with other types of micro-magnetic sensors, GC-CC-302A High-precision Micro-magnetic Basic Sensor has the advantages of high precision, high response rate, high reliability, small volume, low power consumption and strong anti-interference capability, etc. The product uses analog signal output, which is easier to integrate with large user systems and provides higher response rate by the analog signal output.
