• Ultra-compact model.
• PCB surface mounting type.
• High S/N ratio
(High light current / Low leakage current)
• Recommended sensing distance = 1.0 to 4.0 mm
*1 Refer to the temperature rating chart if the ambient temperature
exceeds 25°C.
*2 The pulse width is 10 μs maximum with a frequency of 100 Hz.
*3 Complete soldering within 10 seconds for reflow soldering.

*1. The letter “d” indicates the distance between the top surface of the sensor and the sensing object.
*2. Depends on the installed condition of the Photomicrosensor, the detector may receive the sensor's LED light and/or the external light which
is reflected from surroundings of the Photomicrosensor and /or the background object.
Please confirm the condition of the Photomicrosensor by actual intended application prior to the mass production use.
