Magnetic sensors, such as the HMR3300, are used in both consumer and business applications. Whether it is a robotic arm, a smart phone, a military vehicle or a radar unit, magnetic sensors can be used to measure the direction, the magnitude of a magnetic field, or the angular position of an object. The specific functionality and capabilities of an HMR3300 differs based on the application.

The HMR3300 is an integrated magnetic sensor module that combines a number of components into one package. It includes three hall-effect sensors, a shielded, two-axis magneto-resistor module, and a built-in ASIC (Application Specific Integrated Circuit) integrated circuit, mounted into one single package. The integrated ASIC contains the nonlinearity compensation, low pass filter and signal conditioning circuitry. This enables the HMR3300 to produce highly accurate magnetic field measurements.

The HMR3300 uses a 3-axis magnetic field measurement principle in order to detect the magnetic field vector. The sensor uses three hall-effect elements aligned in the XYZ plane. This configuration ensures a true three-axis field measurement and eliminates crosstalk. The HMR3300 also uses the Advantest’s patented magneto-resistor technology which enables it to measure even extremely low levels of magnetic fields with high accuracy. The motion compensation circuitry helps to reduce errors due to movement.

The HMR3300 is a compact, light-weight and low cost magnetic sensor module. It has an angular resolution of 0.2 degrees and a maximum linear range of 5.5T. It is designed for use in a wide variety of applications including navigation, remote sensing, instrumentation, robotics, entertainment, gaming, consumer electronics, medical, and industrial systems.

The HMR3300 is used in applications such as compass, tilt detectors, electronic compasses, surveillance, robotics, tracking systems and autopilots. It can be used to measure the angular position of an object, measure the magnitude and direction of a magnetic field, or to sense the presence or absence of a permanent magnet. The sensor has high linearity making it ideal for measuring low level signals. It also has a good differential and common-mode noise rejection ratio making it ideal for applications where electrical noise is a problem.

The HMR3300 also has superior temperature compensation characteristics. This makes it suitable for both indoor and outdoor use and ensures reliable operation in a wide range of temperatures. The integrated ASIC is designed to optimize the sensor signal for each application. This ensures superior performance and accuracy for the specific application.

The HMR3300 is well suited for applications such as compasses, absolute angular measurements, Earth’s magnetism measurements, tilt sensing, magnetometers, navigation systems, and many more. It is an ideal choice for applications that require precision, accuracy, and reliability.
