M-A550AR2x Accelerometer Sensor Unit RS422 Interface GENERAL DESCRIPTION The M-A550AR2x is high accuracy and high stability 3 axis accelerometer. This sensor unit is based on Quartz technology (QMEMS) for high accuracy, high stability, small size, and low power consumption. This sensor unit enables wide dynamic range acceleration and vibration sensing. Acceleration, tilt angle and tilt angular velocity is available as user selectable output measurement options. This sensor unit uses the latest technology to improve performance and offer wider sensing bandwidth. With RS422 interface supported for host communication, the M-A550AR2x reduces technical barriers for users to incorporate seismic and vibration sensing, and minimizes design resources to implement control and monitoring applications. This unit is packaged in a water-proof and dust-proof metallic case making it suitable for use in industrial and heavy duty applications. The features of the sensor unit such as high stability, high precision, and small size make it easy to create and differentiate applications in various fields of industrial systems.
