• The lens of this device needs to be kept clean. There are cases that dust, water or oil and so on deteriorate
• Please don’t do washing. Washing may deteriorate the characteristics of optical system and so on.
• In case that an optical filter is set in front of the emitter and detector portion, the optical filter which has the most
• In case that there is an object near to emitter side of the sensor between sensor and a detecting object, please use this
• When the detector is exposed to the direct light from the sun, tungsten lamp and so on, there are cases that it can not
• Distance to a mirror reflector can not be sometimes measured exactly.
• In case that reflective object has boundary line which material or color etc. are excessively different, in order to
• In order to decrease deviation of measuring distance by moving direction of the reflective object, it shall be
• In order to stabilize power supply line, we recommend to insert a by-pass capacitor of 10μF or more
• There are some possibilities that the internal components in the sensor may be exposed to the excessive mechanical
efficient transmittance at the emitting wavelength range of LED for this product (λ = 870 ± 70nm), shall be
recommended to use. Both faces of the filter should be mirror polishing. Also, as there are cases that the characteristics
may not be satisfied 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.
