NOTES
• Using the sensor with a mirror can induce measurement errors. Often, changing the incident angle on
the mirror can correct this problem.
• Keep the sensor lens clean. Dust, water, oil, and
other contaminants can deteriorate the characteristics of this device. Applications should be designed
to eliminate sources of lens contamination.
• If a prominent boundary line exists in the surface
being measured, it should be aligned vertically to
avoid measurement error. See Figure 4 for further
details.
• When using a protective cover over the emitter
and detector, ensure the cover efficiently transmits
light throughout the wavelength range of the LED
(λ = 850 nm ± 70 nm). Both sides of the protective
cover should be highly polished. Use of a protective
cover may decrease the effective distance over
which the sensor operates. Ensure that any cover
does not negatively affect the operation over the
intended application range.
• When measuring the distance to objects in motion,
align the sensor so that the motion is in the horizontal
direction instead of vertical. Figure 5 illustrates the
preferred alignment.
• A 10 µF (or larger) bypass capacitor between VCC
and GND near the sensor is recommended.
• Objects in proximity to the sensor may cause reflections that can affect the operation of the sensor.
• To clean the sensor, use a dry cloth. Use of any liquid to clean the device may result in decreased sensitivity or complete failure.
• Sources of high ambient light (the sun or strong artificial light) may affect measurement. For best
results, the application should be designed to prevent interference from direct sunlight or artificial light.
• Excessive mechanical stress can damage the
internal sensor or lens.
