6. Operating Precautions.
6-1 Basic Precautions
The 3D Image Sensor calculates the distance to a target by measuring the "Time-of-Flight" of
emitted near-infrared rays. Efficiency and reliability of the system may vary depending on actual
operating conditions. Always consider the following factors:
1) High reflectance target:
For example if the target is close to the sensor (closer than 1.2m(3.94ft)) or in case
the sensor receives light reflected by a mirror, the amount of power received increases
considerably and may cause a saturation of the CCD element, resulting in distance
measuring problems or errors.
Besides, the measuring errors can also occur in the target's surrounding area.
2) Intense ambient illumination:
The renge resolution may diminish if a light source (such as sunlight, incandescent light or
heater etc.,) whose emission spectrum, containing near-infrared frequencies
exceeding the specifications, exists inside the detection area of the sensor.
If the light source is too powerful, the CCD element in the sensor unit could saturate,
resulting in distance measuring errors or malfunctions.
3) Fast moving targets:
Fast moving targets may produce distance measuring errors from miss calculation at the
outline of the target.
4) Distance from wall or floor:
If wall or floor is close to the sensor (closer than 1.2 m (3.94ft)), it may produce distance
measuring errors from reflection ofemitted near-infrared rays.
5) Other precautions:
The range resolution may diminish depending on the target's reflectance,
distance to the sensor or position.
6-2 Usage and Storage Conditions
1) The product is designed for indoors use. Please make sure to install in the indoor enviroment.
2) Do not use or store in places where condensation or freezing can occur or near a cooling
or heating system. Do not leave the product exposed to direct sunlight for a prolonged period.
3) This product is neither waterproof nor dustproof. Do not use or store in the following environments:
a) Places with high humidity level, high temperature, low temperature
b) Places exposed to corrosive gas, dust, gasoline, chemicals (including detergent) or water vapor.
c) Places where the sensor would be exposed to condensation or freezing.
4) Avoid exposing the product to shocks, vibration which could cause malfunctions.
5) Do not touch the front panel or the lens with your hands. It could cause reduced performance.
Do not place any cover on the sensor's front panel.
6) Do not use in environments with temperatures above 40℃(104°F), the unit may malfunction.
Always allow for proper ventilation. If installed on a wall or a rack, please leave at least
10cm(3.94inch) between the product's vent and closest wall and allow air to freely circulate around it.
7) When you have to install the transparent material like glass, etc, between the product and the objects,
there is some possibility to cause the distance measurement error because the emitted
near-infrareded rays might be reflected at the trasparent material surface.
Please confirm at the actual installed condition.
