Motor vehicle chassis sensor

摘要

A vehicle chassis sensor assembly comprising a housing member defining a sensor cartridge slot, a rotatable shaft with a magnet and retained in a sleeve, and a rotatable arm coupled to the shaft. A sensor cartridge is mounted in the slot through the interior of a connector socket and an opening between the slot and the connector socket. A plate on the sensor cartridge covers the opening. The sensor cartridge includes a terminal header and a separate board mounted to the terminal header. The board includes the sensor. Deformable posts on the terminal header and the sensor assembly extend through respective apertures in the board and the terminal header for securing the board and the sensor cartridge to the terminal header and the sensor assembly respectively.
