7 Data Sheet

NOTES

• Keep the sensor lens clean. Dust, water, oil, and

other contaminants can deteriorate the characteris-

tics of this device. Applications should be designed

to eliminate sources of lens contamination.

• 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.

• Objects in proximity to the sensor may cause reflec-

tions that can affect the operation of the sensor.

• Sources of high ambient light (the sun or strong arti-

ficial light) may affect measurement. For best

results, the application should be designed to pre-

vent interference from direct sunlight or artificial light.

• Using the sensor with a mirror can induce measure-

ment errors. Often, changing the incident angle on

the mirror can correct this problem.

• If a prominent boundary line exists in the surface

being measured, it should be aligned vertically to

avoid measurement error. See Figure 5 for further

details.

• When measuring the distance to objects in motion,

align the sensor so that the motion is in the horizontal

direction instead of vertical. Figure 6 illustrates the

preferred alignment.

• A 10 µF (or larger) bypass capacitor between V

and GND near the sensor is recommended.

• To clean the sensor, use a dry cloth. Use of any liq-

uid to clean the device may result in decreased sen-

sitivity or complete failure.

• Excessive mechanical stress can damage the

internal sensor or lens.
