Description

The Siderion RM3100 is a high-performance, ultra-low power 3D magnetic sensor designed for precision compassing, contactless angle measurement, and motion detection in battery-powered applications. Leveraging PNI’s patented Magneto - Inductive (MI) technology, the RM3100 delivers exceptional accuracy, stability, and immunity to environmental interference, such as stray magnetic fields and temperature variations without requiring factory calibration. The RM3100 combines cutting-edge sensor technology with energy efficiency, making it the ideal choice for designers seeking high-performance magnetic sensing in compact, power-sensitive applications. Its JST-GH connectors make it ideal for integration with Pixhawk or other autopilot systems. The RM3100 operates across a temperature range from -40°C to +70°C.
