gp2y3a002k0f sheet no.: e4-a01301en notes advice for the optics ? the lens of this device needs to be kept clean. there are cases that dust, water or oil and so on deteriorate the characteristics of this device. please consider in actual application. ? 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. advice for the characteristics ? in case that an optical filter is set in front of the emitter and detector portion, the optical filter which has the most efficient transmittance at the emitting wavelength range of led for this product ( = 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. ? in case that there is an object near to emitter side of the sensor between sensor and a detecting object, please use this device after confirming sufficiently that the characteristics of this sensor do not change by the object. ? when the detector is exposed to the 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 is not exposed to the direct light from such light source. ? distance to a mirror reflector can not be sometimes measured exactly. in case of changing the mounting angle of this product, it may measure the distance exactly. ? in case that reflective object has boundary line which material or color etc. are excessively different, in order to decrease deviation of measuring distance, it shall be recommended to set the sensor that the direction of boundary line and the line between emitter center and detector center are in parallel. ? in order to decrease deviation of measuring distance by moving direction of the reflective object, it shall be recommended to set the sensor that the moving direction of the object and the line between emitter center and detector center are vertical. advice for the power supply ? in order to stabilize power supply line, we recommend to insert a by-pass capacitor of 10 f or more between vcc and gnd near this product. (incorrect) (correct) (incorrect) (moving direction) (correct) (moving direction) notes on handling ? there are some possibilities that the internal components in the sensor may be exposed to the excessive mechanical stress. please be careful not to cause any excessive pressure on the sensor package and also on the pcb while assembling this product. 6
