D7S

Vibration Sensor

Helps Prevent Fire and Other Second-

ary Disasters after an Earthquake.

The World’s Smallest Class Size

Seismic Sensor.

• Using the SI value, which has a high correlation with the seismic

intensity scale that indicates the magnitude of an earthquake, provides

higher-precision judgment of seismic intensity scales.

• The 3-axis acceleration Sensor and OMRON’s unique SI value

calculation algorithm achieve surface-mountable compact modules

and low power consumption.

• Higher degree of freedom for incorporation into devices and prolonged

operation on battery power.

• Shutoff output terminal (INT1) operates equivalent to a conventional

mechanical vibration sensor and ensures compatibility with

mechanical vibration sensors.

Sensor with communications from external devices.
