■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 is set in front of the emitter and detector portion, the protection cover which has the most
efficient transmittance at the emitting wavelength range of LED for this product (λ=870nm±70nm), shall be
recommended to use. The face and back of protection cover should be mirror polishing. Also, as there are cases
that the characteristics may not be satisfied with according to the distance between the protection cover and this
product or the thickness of the protection cover, please use this product after confirming the operation sufficiently
in actual application.
[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.
●When the detector surface 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.
●Distance between sensor and mirror reflector can not measure 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 parallels,
it is possible to decrease deviation of measuring distance.
(Incorrect) (Correct)
●In order to decrease measuring error by moving direction of object, we recommend to mount the sensor like
below drawing.
(Incorrect) (Correct)
(Moving direction) (Moving direction)
●In order to stabilize power supply line, we recommend to connect a by-pass capacitor of 10μF or more between
Vcc and GND near this 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 for
washing.
●There are some possibilities that the sensor inside the case package with lens may be exposed to the excessive
mechanical force. Please be careful not to cause any excessive pressure on the case package with lens and also on the
sensor’s PCB at the assembly and inserting of the set.
