Abstract

A vehicular camera assembly includes a camera housing having a front housing portion and a rear housing portion. The front housing portion accommodates a lens. A first printed circuit board (PCB) is disposed at the front housing portion, with an imager disposed at a front side of the first PCB and a first electrical connector disposed at a rear side of the first PCB. A second PCB has a second electrical connector disposed at a front side. Circuitry of the second PCB is electrically connected to circuitry of the first PCB via electrical connection of the first and second electrical connectors. A plurality of terminal pins has a first end interior the camera housing and a second end at a connector portion of the rear housing portion. The connector portion is configured for connecting to a vehicle wiring connector when the vehicular camera assembly is installed at a vehicle.
