Force-Rebalance Digital SMD MEMS Accelerometers
Miniature, digital and high bias and scale factor repeatability
SMD MEMS accelerometers for dynamic applications
High stability in dynamic applications
AXO® is a unique family of high performance digital closed-loop MEMS acceleration sensors housed in a SMT package. The force-rebalance architecture of AXO® accelerometers makes them extremely linear and insensitive to vibrations. AXO® provide best in-class composite bias repeatability and scale factor repeatability under demanding temperature and dynamic conditions of industrial, land, railway and naval applications. AXO® very low noise and excellent bias stability make them very well suited to precision attitude, guidance and motion control, as well as GNSS-aided positioning and navigation applications.
24-bit digital interface and SMD sensors
AXO® 24 bit SPI interface and small hermetic SMT package eases their integration and reduces the bill of materials and complex temperature modeling at the system level compared to incumbent tactical-grade analog quartz accelerometers. It also overpasses all commercially-available MEMS acceleration sensors for dynamic applications. The AXO® accelerometers are ideally complemented by the GYPRO® high performance digital gyros product line.
