Abstract
The present invention relates to an infrared sensor (20) of the type comprising a support plate (22) provided with a printed circuit carrying a plurality of elements (23) sensitive to infrared waves and a dome (21) designed to cover said sensitive elements. This sensor is characterized in that: cutouts (27) are made in the support plate (22) around each sensitive element, each of these cutouts delimiting a tongue (28). These tongues are designed to be deployed outside the plane (P) of the support plate and to interact with the dome (21) in such a way that they adopt a defined position with respect to one another. The sensor according to the present invention is more particularly intended to equip automobile courtesy lights and to form part of an antitheft and/or centralized door-locking device.
