Abstract
A vehicular camera includes a camera housing having front and rear camera housing portions. An imager is disposed at a printed circuit board. A lens assembly is disposed at the front camera housing portion and accommodates at least one lens. The front camera housing portion is formed of a material having a first Coefficient of Thermal Expansion (CTE). At least two attachment elements are disposed at the front camera housing portion and are formed of a material having a second CTE that is less than the first CTE of the front camera housing portion and that is less than 10 ppm/° C. The printed circuit board is mounted at the attachment elements via fasteners threadedly engaging respective ones of the at least two attachment elements. The front camera housing portion and the attachment elements cooperate to decrease temperature-induced movement of the printed circuit board relative to the at least one lens.
