The most accurate Low-SWaP magnetic sensor on the planet.
RM3100 Magnetic Sensor
Incredible resolution with low power, low mass, small size and large dynamic range.
Impeccable signal to noise, no drift, and precise magnetic field measurements make integration of the RM3100 sensor simple and ideal for underwater, air, satellite, and spacecraft application.
Getting accurate navigation and position data depends on having accurate magnetic field measurement to begin with. Unlike traditional Hall-effect sensors, the RM3100 magneto-inductive sensor has over 23 times better resolution and 33 times less noise resulting in far more precise data outputs.
Stable and reliable over time and temperature and extremely radiation tolerant.
I2C and SPI interfaces.
Proven in real world across a wide range of applications requiring a Low-SWap heading sensor.
