SMA131 | Acceleration sensor for non-safety relevant applications

Economical through 3 power-saving modes, which give a very low power consumption

The SMA131 detects acceleration in three perpendicular axes (axyz) and allows tilt, motion, vibration or shock sensing regardless of the sensor mounting orientation

The SMA131 is a digital 14-bit accelerator with different measurement ranges. The sensor combines our knowledge from consumer and automotive electronics.

Numerous programming options, a low signal noise and very small footprint make the SMA131 a highly versatile and easily applied acceleration sensor for non-safety automotive applications.
