Omron EE-SY671 Photomicrosensor
Omron EE-SY671 is a horizontal reflective photomicrosensor designed for short-range sensing from 1 to 5 mm. Light is directed toward the target and the returned optical signal is used to establish the sensing state without an opposing receiver. The sensor provides an NPN output with selectable Light-ON or Dark-ON operation and runs from 5 to 24 VDC. Current consumption is specified at 40 mA, while the output supports a maximum load current of 100 mA. A red light indicator provides visual operating status, and a 4-pole connector provides the electrical interface. For horizontal short-range reflective sensing, the EE-SY671 forms part of the reflective photomicrosensor range from Omron sensing products.

The Omron EE-SY671 Photomicrosensor uses a horizontal reflective sensing arrangement across a specified 1 to 5 mm range. Light is directed toward the target and the returned optical signal is evaluated from the same sensing side, allowing the sensor to establish the target condition without an opposing optical element. The unit operates from 5 to 24 VDC and provides an NPN output with selectable Light-ON or Dark-ON operation. Current consumption is specified at 40 mA. The output supports a maximum load current of 100 mA, with residual voltage listed as 0.8 V maximum at a 100 mA load and 0.4 V maximum at 40 mA. A red light indicator provides visual operating status, while the optical arrangement is non-modulated. Electrical connection is provided through a 4-pole connector.
The EE-SY671 uses PBT for the case and polycarbonate for the emitter and receiver sections. Operating temperature is specified from -25°C to 55°C, while storage extends from -30°C to 80°C. Operating humidity ranges from 5% to 85%, with storage humidity from 5% to 95%. Mechanical resistance includes vibration from 20 to 2,000 Hz under the stated test conditions and shock resistance of 500 m/s² three times in each X, Y, and Z direction. The enclosure carries an IP50 rating. Its horizontal orientation provides a compact arrangement where the target approaches the sensing face from the specified direction. For a related vertical model using the same 1 to 5 mm reflective range and NPN output, see the Omron EE-SY672.
