Closed-loop digital accelerometer for high dynamics industrial applications

TDK Corporation has released a new product – the Tronics AXO300 accelerometers platform. After the successful launch of AXO315 for avionics applications, AXO305 for land and marine positioning systems, and AXO301 for railway applications and inclination measurement, Tronics extends its portfolio with AXO314, a high-performance digital MEMS accelerometer with ±14g input range for industrial applications operating under shock and vibration.

Empowered by the company’s industry-unique closed-loop architecture that provides excellent linearity and high vibration rejection, AXO314 offers a low-SWaP, digital, and cost-effective alternative to bulky and expensive tactical-grade quartz accelerometers.

With its one-year composite bias repeatability of 1mg and bias instability of 4µg, the device provides a robust, miniature, and precise acceleration sensing solution for dynamic systems exposed to harsh environments and needing a high level of stability and reliability.

Combined with Tronics’ high-stability MEMS gyro GYPRO4300, which shares the same SMD J-lead package for excellent thermal behaviour and the same 24-bit SPI interface, AXO314 is the perfect candidate for integration into multi-axis tactical-grade IMUs, and INS used in land, sea, and air surveying and mapping applications, and GNSS-assisted positioning systems for aerial and ground vehicles.

AXO314 is not classified under dual-use export control and complies with REACH and RoHS standards. Similarly to all products from the company’s high-performance MEMS inertial sensors portfolio, these accelerometers are factory-calibrated to provide a highly accurate output over their temperature range. Raw data output can also be selected to allow customer-specific compensation strategies.

It will be exhibited for the first time at Intergeo 2024, booth G1.07, from September 24 to 26, 2024.
