XENSIV™ KP405 pressure sensor for side crash detection (SAB), pedestrian impact detection, and front crash detection in a DFN package The KP400 is a monolithically integrated pressure sensor with a programmable PSI5 interface, designed for passive safety vehicle systems. It provides fast reaction times and helps fulfill current and future safety tests. Used in side airbag and pedestrian protection applications, it offers a signal pulse proportional to pressure changes, with an amplitude independent of ambient pressure. It's ISO 26262-compliant and offers excellent cost performance.
