SMA130

Application & Technical Summary

The SMA130 detects acceleration in three perpendicular axes (axyz) and allows tilt, motion, vibration or shock sensing regardless of the sensor mounting orientation.

The SMA130 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 SMA130 a highly versatile and easily applied acceleration sensor for non-safety automotive applications.
