The SEP8736 series, from Honeywell, are infrared emitting diodes (IREDs) in a side-looking plastic package. The IR emitting diode is molded inside the grey plastic package. They SEP8736 series offer the narrow emission pattern available from T-1 packages in a side emitting device. They also offer longer coupling distances to other standard side-emitting IREDs. This makes them ideal for applications such as touch screens.
