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 ( = 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 F (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.
