Panasonic recommends a 4-layer PCB with a solid ground plane, and the sensor should be placed at least 1.5 mm away from any metal components or traces to minimize interference.
The AHES3190 is designed to withstand vibrations up to 10 G (10 Hz to 2 kHz) and shocks up to 100 G (11 ms, half-sine wave). However, it's recommended to follow proper mounting and installation procedures to ensure reliable operation.
While the AHES3190 is rated for operation up to 85°C, Panasonic recommends derating the sensor's output by 0.5% per degree Celsius above 60°C to ensure accurate measurements.
The AHES3190 has built-in EMI shielding, but it's still recommended to follow proper PCB design and layout practices, such as using a ground plane and shielding, to minimize EMI effects.
Panasonic recommends a two-point calibration procedure, where the sensor is calibrated at 0 Gauss and a known magnetic field strength (e.g., 1.3 Tesla). The calibration data should be stored in an external memory or microcontroller.
