Application

1.Application products:

North seeking MEMS Gyro ER-MG2-100

2.Package Information

2.1 Adopt 48 pin ceramic package

Figure 1 encapsulates the diagram

Figure 2 Package size diagram

2.3 Axis of rotation

Fig.3 Axial diagram of rotation detection

The MEMS gyro is a single-axis high performance gyroscope that detects the rotary axis perpendicular to the chip surface.

Counterclockwise rotation along the axis of rotation is positive and clockwise rotation along the axis of rotation is negative.
