The EE-SY310 is a compact reflective photomicrosensor designed for non-contact object detection. It operates on a wide supply voltage range from 4.5 to 16 VDC and features a recommended sensing distance of 5.0 mm. This sensor integrates a detector element, amplifier, and temperature compensation circuit into a single IC, allowing for direct connection with C-MOS and TTL logic. As a Dark ON model, its output is active when no light is reflected. The EE-SY310 is suitable for various presence and absence detection applications in industrial and consumer electronics.
