GP2Y1010AU0F
● Notes
1 Connection of case and GND
Case material use conductive resin as cover case {printed model No.} and metal {test terminal side}
as bottom cover. The metal case connects with GND in sensor.
2 Cleaning
Please don’t do cleaning, because there is a case that this device is not satisfied with its characteristics
by cleaning.
3 Pulse input range
Please subject to recommendation as regard input condition for LED in order to keep reliability.
4 Dust adhesion
There is a case that this product does not detect the dust density correctly, since the dust adhered to
the inside of the dust through hole may project into the detecting space which consist of emitter and
detector light axis. Please take the structure and mechanism of the equipment into consideration to
avoid the influence of adhered dust. And when the dust is adhered, please consider the maintenance
such as vacuuming or blowing off the dust by air.
In addition, please pay attention to structure and placing location of the application to avoid any
adhesive particle like oil, etc. to gets into the device. If it sticks to optical part, malfunction may occur.
5 Light output
In circuit designing, make allowance for the degradation of the light emitting diode output that results
from long continuous operation. (50% degradation/5 years)
6 Sensitivity adjustment VR
VR for sensitivity adjustment is set up at shipping from sharp. Please do not touch the VR or
Electro-optical characteristics specified on the specification will be invalid.
7 Resolution
Please do not disassemble the device such as removing tapping screw and so on. Even if the device
is reassembled, it may not satisfy the specification.
8 Application to fire alarm
Please do not use this device for a fire alarm application. When using this device to application other
than air purifying and equipment with air purifying function, please inform us before usage.
9 Noise influence
If the sensor is located close to noise generator (ex. Electric dust collector, etc. ), the sensor output
may be affected by leaded noise. On top of that noise from power supply line also may affect the
sensor output. When desinging the system, please consider the effect from noise.
10 Vibration influence
The sensor may change its value under mechanical oscillation. Before usage, please make sure
that the device works normally in the application.
11 Incident light influence
There is a case that the sensor output may be affected when outer-light comes through dust through
hole on printed side. In order to avoid any influence from outer-light, please locate the printed side
of sensor facing to inside of the application.
12 When inside of the sensor is moisturized, this product does not keep its proper function. Please
design the application so that moisturization of the sensor does not happen.
