NAS

The MicroTesla Analog Surfacemount Sensor is the newest version of our analog sensor. In addition to MicroTesla’s proprietary magnetometer technology, the NAS uses fully optimized surfacemount circuit boards.

The new one board NAS is mounted to the chassis using the Ulti-Pak method for improved shock and vibration, and thermal performance.
