AXO315 High-Performance Closed-Loop MEMS Accelerometer

Tronics’ AXO315 accelerometer with digital interface has a one-year composite bias repeatability of 1 mg under severe environments

Image of Tronics' AXO315 High-Performance Closed-Loop MEMS AccelerometerTronics’ AXO315 closed-loop MEMS accelerometer offers a performance-equivalent alternative to incumbent analog force-rebalance quartz and mechanical servo-accelerometers at a fraction of their size, weight, and cost. The 24-bit SPI eases its integration and reduces the e-BOM.

The AXO315 has a one-year composite bias repeatability of 1 mg under demanding temperature and vibration conditions. It is free from dual-use export control, according to Annex 1 of Council Regulation (EC) No 428/2009. The AXO® acceleration sensors are ideally complemented by GYPRO® high-performance digital gyrometers and are REACH and RoHS compliant.

The AXO315 is a very low noise sensor that provides excellent linearity and one-year composite scale factor repeatability over an extended temperature range. This accelerometer is well suited to precision attitude, guidance, and motion control and GNSS-aided positioning applications in demanding industrial, land, railway, and naval environments.

Features
