The Omron EE-SY671 is a compact reflective photomicrosensor designed for short-range detection in tight industrial setups. Its horizontal form factor makes it suitable for mounting in narrow spaces, while the reflective sensing method ensures detection at distances between 1 and 5 mm.
This sensor features a selectable Light-ON/Dark-ON mode and delivers an NPN open collector output, making it flexible for a wide range of control circuits. It consumes just 40 mA and supports up to 100 mA load current. A red LED indicator provides visual feedback during operation. The connector-type interface enables quick and clean installations.
Housed in a durable PBT body with PC emitter and receiver covers, the EE-SY671 is built to withstand vibrations and shock. It is rated IP50 and operates in ambient temperatures from -25°C to 55°C. Ideal for object detection on conveyors, labeling systems, or packaging lines.
