The MMC5603NJ is a 3-axis Hall Effect/Magnetic Sensor that is designed to detect the Earth's magnetic field in industrial, automotive, and consumer applications. The device is monolithic, offering high performance and low cost, and can measure Magnetic Field up to 30 G with low noise and low power consumption. The footprint of the sensor is tiny and is designed to mount directly onto general-purpose PCBs (Printed Circuit Boards). This board mount magnetic sensor helps in magnetic field detection and is ideal for applications such as electronic compass systems, biomedical equipment, handheld devices, automotive applications, and mobile consumer electronics.
