Abstract:
1. A proximity sensor comprising: a printed circuit board (PCB); a first cup and a second cup embedded in the PCB, at least one of the first and second cups comprising an annular tapering wall that is coated with a reflective material; an electromagnetic radiation transmitter operably mounted in the first cup; an electromagnetic radiation receiver operably mounted in the second cup; encapsulant, which is transparent to electromagnetic radiation transmitted by the transmitted, encapsulating the transmitter and the receiver, the encapsulant substantially filling the first cup and the second cup, the encapsulant further forming at least one lens above at least one of the first cup and the second cup; an opaque layer, which attenuates electromagnetic radiation transmitted by the transmitter, positioned in overlying relationship with the PCB and having a first aperture aligned with the first cup and a second aperture aligned with the second cup; and at least one molding ring positioned in overlying relationship with at least one of the first aperture and second aperture, the at least one molding ring comprising a laterally extending rim portion and an upright rim portion that are used to form the at least one lens above at least one of the first cup and the second cup, wherein the at least one molding ring is situated between the opaque layer and the PCB.
