Impact Sensor: Description and Operation
AIRBAG SENSOR
The airbag control module and side airbag sensor contain an electric sensor and a safety sensor.
The electric sensor consists of a semiconductor type sensor which senses the deceleration caused by collision in terms of change in the electrical
resistance of the impact sensing circuit.
The safety sensor is a pendulum type sensor. If the sensor receives a frontal or side impact exceeding a certain limit, the mass in the sensor move in the
direction opposite to the impact direction to turn the switch ON.
