A proximity sensor arrangement comprises an optical barrier (1) being placed between a light emitting device (2) and a photo-detector (3). The light emitting device (2), the photo-detector (3) and the optical barrier (1) are covered by a cover (4). The optical barrier (1) is being designed to block light (21) emitted from the light emitting device (2) to the photo-detector (3) and reflected (22) by the cover (4) by means of specular reflection. Furthermore, the optical barrier (1) is being designed to pass the light (22) emitted from the light emitting device (2) to the photo-detector (3) via the cover (4) and scattered (23) on or above a first surface (41) of the cover facing away from the light emitting device (2) and the photo-detector (3). |
