M-XDR series is a Z-axis MEMS angular rate sensor (gyroscope) with a maximum range of up to ±2000°/s, and its digital output interface complies with the SPI slave protocol. The angular rate data is in 24-bit two's complement format.
M-XDR series is suitable for high-performance industrial applications. It uses an advanced differential MEMS design, which can eliminate the effects of linear acceleration and can operate in harsh environments with extreme shock and vibration.
The specially designed package can be soldered through the bottom or the front to simplify the system's structural design. When mounted on the bottom, the sensitive axis is perpendicular to the main circuit board. When mounted on the front, the sensitive axis is parallel to the main circuit board.
