The Omron EE-SX673P is a through-beam photoelectric sensor from the SX67 series, with a 5 mm sensing window and PNP output. It switches at up to 3 kHz and responds in 0.17 msec — fast enough for counting small parts on a pick-and-place or detecting edge positions in a labeler. The body is PBT, IP50 rated, and mounts close to the target (no fiber-optic extension). Supply: 5-24 V DC, loads up to 50 mA. Selectable Light-On/Dark-On covers both break-beam and pass-beam logic.
What the key ratings actually mean for fit
5 mm sensing distance is the gap between emitter and receiver — the object must pass through that slot. Minimum detectable object is 2 mm x 0.8 mm opaque, so it sees small die-cuts or cap seals. The 3 kHz switching frequency means it can keep up with a belt running at several meters per second if the target is narrow enough. Response time at 0.17 msec confirms it won't miss a fast-moving gap. Output short-circuit protection is built into the PNP stage — if a wiring mistake shorts the load line, the sensor survives. On a field swap, that saves a trip back to the van.
