■Notes
[Advice for the optics]
●Lens of this device shall be kept cleanly. There are cases that dust, water or oil and so on deteriorate the characteristics
of this device. Please consider in actual application.
●In case that protection cover is set in front of this sensor , the protection cover shall be recommended to use material
which doesn’t scatter light and be matt finish. And the protection cover which has the most efficient transmittance
at the emitting wavelength range of LED for this product (λ=850nm±70nm). And this protection cover is recommend to
be flat. And this protection cover shall be recommended to be parallel to the emitter and detector portion. In case that
protection cover is set in front of this sensor, It emits reflected light from this protection cover. If this reflect light reaches
in detector portion, the output distance of this product may be changed. The output distance characteristics of this product
may be changed with according to material (①) or transmittance (②) or the thickness (③) or the distance
between the protection cover and this product (④) or the angle between surface and back (⑤) or the angle between this
cover and this sensor(⑥). In case that protection cover is set, please design to consider that this reflective light is
minimized. And it shall be effective to put light shield wall between emitting lens and receiving lens as shown in below.

exisitence【*】
Direct reflective light becomes large as Distance from sensor to protection cover and thickness of this cover become large.
In case thickness is 2mm and distance is 1mm, measuring distance is changed shift larger from actual distance than other
condition. It shifts can make small by using installation of light shield【*】and compensation function【**】.
【*】Noted for installation of light shield
Inner distance between lens of detector and lens of emitter is around 0.6mm (reference). So the width of light shield is
recommended to be less than 0.6mm. In case the width of light shield is longer than inner distance, measuring distance
is changed by Shield a part of emitter lens or detector lens. Please confirm that there is no problem under the actual
equipment. And In case between protection cover and light shield or between light shield and this sensor exists space,
The effect of light shield is small because light from emitter leaks. The light shield wall is recommended to use the
material that have the low transmittance at the emitting wavelength range of LED for this product (λ=850nm±70nm).
When the material of light shield wall is hard, and the power stress in which it is added to this product is large, measuring
distance may shift from actual distance.

【**】Noted of compensation function
This product has the function which rectifies error shift by the direct reflective light from protection cover. The accuracy
after compensation is based on a protection cover or its installation condition. This function can be active when it set
correction factor in this product by I 2 C or E-fuse. Please refer to application manual about the detail of this function.
Neither installation of a light shield wall nor use of a compensation function guarantees the distance characteristic.
These improve error shift of the distance characteristic.
Regardless of use of a light shield wall or a compensation function, please use it after confirming with customer’s product.

[Advice for the characteristics]
●In case that there is an object near to light exits of the sensor between the sensor and the detected object, please use
this device after confirming sufficiently what the characteristics of this sensor do not change by the object.
●This product has the function to remove disturbance light by the cancellation function of ambient light, a visible light cut
lens, etc. But when the detector receive direct light from the sun, tungsten lamp and so on, there are cases that it can not
measure the distance exactly. Please consider the design that the detector does not receive direct light from such light
source. When you operate the customer’s set installing this product by the remote control, please consider soft that the
output of this product being disregarded at the time of remote control operation by software.
●Distance between sensor and mirror reflector cannot be measured exactly.
●In case that reflective object has boundary line clearly, there is cases that distance can not measure exactly.
At that time, if direction of boundary line and the line between emitter center and detector center are parallels,
it is possible to decrease deviation of measuring distance.

●For satisfying the specification of the electro optical characteristic, it is necessary to install a flat surface of object in
vertical of emitted light, and it is necessary to reflect the whole emitted light as shown in the following figure. As shown
in the example of directional angle of emitting beam, The angle is around 6 ° (±3°) where emission becomes 10% of
peaks. The object needs to exist in whole around 10 degrees (±5 degrees) area including the variation of peak position.
For example, when the object is in 50 cm, it is necessary to install the object of at least 9cm diameter parallel to the
surface of this sensor as follows. However above example doesn’t guarantee specification, please use it after confirming
with customer’s product.

[Notes on handling]
●Please don’t do washing. Washing may deteriorate the characteristics of optical system and so on.
Please confirm resistance to chemicals under the actual usage since this product has not been designed against washing.
●Please use this product under the condition that applied stress to the connector below 0.49N. And, harness is pulled
in the state where it attached this sensor, or please be careful so that the stress more than the above may not be added to
this sensor.
●This product have the parts that mount to the substrate by soldering . Since there is a possibility that a solder mounting
part may break when this product is used, the stress more than 4.9N should not be added to this product.
