KP106 is a pressure sensor system for the detection of side crashes in passenger cars.
In this application, the pressure sensor is assembled in a module located within
the car’s side doors. When the door is compressed due to a side impact, the KP106
provides a signal pulse which is proportional to the pressure change inside the door.
The height of the signal pulse depends on the relative pressure change. Therefore the
output signal is independent of the ambient pressure.
