The Omron EE-SX672P is a through-beam photoelectric sensor from the EE-SX67 series, packaged as a T-slot body with a right-angle sensing face. It detects a 2 mm × 0.8 mm opaque object at up to 5 mm — that is a very short gap, sized for edge detection, flag sensing, or registration mark pickup on a moving web or part carrier. Output is PNP, sourcing up to 50 mA, with selectable Light On / Dark On switching. The 3 kHz switching frequency means it can resolve events about every 0.33 ms — fast enough for counting parts on a moderate-speed conveyor or indexing a rotary table. Supply range is 5–24 V DC, so it runs on common logic supplies or 24 V industrial rails. The solder terminal connection suits a fixed installation where a cable gland or connector is not required.
Because this is a niche T-slot through-beam with a short 5 mm range, it is not a high-volume commodity.
