Omron EE-SY671 is a 1–5 mm reflective photomicrosensor with 940 nm infrared LED, NPN output, 5–24 VDC supply and adjustable sensitivity.
The Omron EE-SY671 is a horizontal diffuse-reflective photomicrosensor with built-in sensitivity adjustment and an NPN open-collector output. It senses a 15 × 15 mm white paper target at 1–5 mm using a 940 nm infrared LED, and supports 5–24 VDC operation with 100 mA maximum output load. Its IEC IP50 case uses a special connector or direct soldering; current supply status is recorded as Unknown.

Engineering suggestions require suitability checks for your installation.
A compact mechanism may need to detect a small nearby target without a separate receiver path.
Set the built-in sensitivity adjuster for the actual target reflectance and confirm the 1–5 mm sensing margin at the installed angle.
A fixture may need a discrete presence signal for a small transparent or opaque item.
Use the NPN output with a compatible controller input and verify target size, ambient light, output load and Light-ON/Dark-ON wiring.
