The most accurate Low-SWaP magnetic sensor on (and off) the planet

RM3100
Magneto-Inductive Magnetometer

Incredible resolution with low power, low mass, small size and large dynamic range.

Z

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.

Z

The RM3100 can deflect fields as low as 2.7 nT at 1Hz, with a noise floor of 4 pT /√Hz at 1Hz. It also has a linear response over a range of 100,000 nT. The RM3100 has been tested for various environmental conditions, such as thermal shock, mechanical shock, radiation, and thermal cycles, and has shown strong performance and stability.

Z

The RM3100 delivers impeccable signal-to-noise, drift-
free, precise magnetic field measurements, ideal for
underwater, ground, air, and space applications. It offers pinpoint resolution with low power, low mass, small size and large dynamic range features.

Z

Installed in over tens of millions of devices worldwide, and trusted by leading military and commercial companies for use in key equipment. And it’s tested and approved by NASA.

Z

Stable and reliable over time and temperature and extremely radiation tolerant, the RM3100 has I2C and SPI interfaces.
