The Omron EESX672WR1M is a through-beam photomicro sensor from the EE-SX67 series, built for tight-space presence detection where the emitter and receiver align across a 5 mm gap. It switches NPN output at up to 100 mA, with a 1 ms response time, and operates from 5 to 24 VDC. The housing is a compact 26 × 26 × 29 mm block with a 1 m cable termination, rated IP50 for dry indoor environments.
The 5 mm sensing distance is fixed by the through-beam slot — the object must break the infrared beam between the two arms. That makes it a positive-position detector, not a proximity sensor. The NPN output pulls low when the beam is interrupted (dark-ON) or restored (light-ON), selectable via wiring. The 1 ms response covers most high-speed counting or indexing applications, but not sub-millisecond events like high-RPM shaft keyways. The 100 mA load current is enough to drive a PLC input or small relay directly, but not a contactor coil without an interposing relay.
The 26 × 26 × 29 mm body mounts via two through-holes on the side flanges. The 1 m cable exits the rear; route it clear of moving parts and avoid sharp bends at the strain relief. The IP50 rating means it is suitable for control cabinets or dry machine zones, but not washdown areas — a splash or condensation event will compromise the optics. The infrared LED is not visible to the eye; use a test piece to confirm beam alignment during commissioning.
