SMA731 | Acceleration sensor for vibration control

SMA731

Reliable operation due to self testing capability and digital data transmission

The single-axis low-g SMA731 accelerometer (ax) is designed for use in active suspension systems to sense the chassis acceleration.

SMA731 can be used to measure acceleration of a body along the z-axis along with its pitch and roll movements. The sensor also measures static and dynamic accelerations.

The control unit receives all the sensor signals and continuously adjusts the damping forces to a comfortable and safe level. The sensor can also be used for other applications, including tilt measurement for powered trunk lids. The sensor is developed in accordance to ISO26262 for ASIL B system use.
