KP204

XENSIV™ - KP204 pressure sensor for Side Crash and Pedestrian Impact Detection

The Infineon XENSIV KP204 is a pressure sensor for the detection of side crashes in passenger cars. In this application the pressure sensor is assembled in a door module located within the car’s side door. When the door is compressed due to a side impact, the KP204 provides a signal pulse which is proportional to the pressure change inside the door (Δp/p0). During the normal operation mode there is a continuous internal range check.
