AXO®301
High Resolution ±1g MEMS Accelerometer with Digital Interface
High resolution and high stability in vibrating environments
AXO®301 is a single-axis, high resolution, closed-loop MEMS accelerometer with ± 1 g input range that offers a digital, cost-effective, and low-SWaP alternative to quartz accelerometers.
AXO®301 is perfectly suited to acceleration and inclination measurements for applications operating in highly vibrating environments, such as high-end industrial and railway systems.
The 24-bit digital SPI interface eases the integration of AXO®301 into high performance inclinometers and motion control systems. The built-in self-test ensures initial verification of the sensor’s integrity and continuous in-operation functionality test.
