This product is an angular velocity sensor that uses the phenomenon of Coriolis force, which is generated when a rotational angular velocity is applied to the vibrator.

■ Features

1. Ultra-small and ultra-lightweight

2. Quick response

3. Low driving voltage, low current consumption

4. Lead type: SMD

5. Reflow soldering (standard peek temp. 245 deg. C)

■ Application

1. One sensor detects rotation on one axis. If two axes are to be detected in the same equipment, two different types of sensors (EMC-03RC and EMC-03RD) should be used.

2. To reduce the effect of temperature drift (due to change of ambient temperature), a high pass filter must be connected to sensor output to eliminate DC component.

3. To suppress output noise component around 30-33kHz (resonant frequency of sensor element), a low pass filter which has higher cut-off frequency than required response frequency must be connected to sensor output.
