A sensor comprising a light emitter and light detector coupled directly with or formed directly on a lead frame and directly covered and encapsulated by a layer of light transmissive compound. A gap in the light transmissive compound between the light emitter and the light detector wherein in some embodiments the gap can be filled with a light blocking barrier material.

Proximity sensor with light inhibiting barrier comprising a gap having a cross-section with parallel walls substantially perpendicular to the top surface of an optically transmissive material

A sensor comprising a light emitter and light detector directly covered and encapsulated by a layer of light transmissive compound. A gap in the light transmissive compound between the light emitter and the light detector filled with a light blocking barrier.

Proximity sensor with light blocking barrier comprising a gap having a cross-section with parallel walls between emitter and detector

A sensor comprising a light emitter and light detector directly covered and encapsulated by a layer of light transmissive compound. A gap in the light transmissive compound between the light emitter and the light detector filled with an infrared ink. In some embodiments, an infrared ink can cover at least a portion of a top surface of the sensor and define apertures above the light detector and/or light emitter.

Proximity sensor with infrared ink coating

A sensor comprising a light emitter and light detector directly covered and encapsulated by a layer of light blocking compound. The light blocking compound can be thick enough between the light emitter and light detector to block substantially all light emitted by the light emitter from reaching the light detector directly, but be thin enough above the light emitter and light detector to allow at least some level of light emitted by the light emitter to escape out of the sensor, be reflected by another object, re-enter the sensor, and survive passing through the light blocking compound to enter the light detector.
