※The distance output of GP2Y8E01 shall be the spot size of photo detector.
The spot size will be bigger in coming near, and the spot size will be smaller in going far.
This means that the distance output is relative value because spot size also changes by the size of reflective object.

(1) LED current (Bank1 Addr = 0x32, 0x33)
It needs to be set same value in both 0x32 and 0x33 in register.
LED emits light more than 0x01 in both registers. And driving current becomes large, so that a register
value is enlarged.
Driving current is about 30 mA per value 1.
Standard operation condition is typ.90mA.
It is possible to set up LED current between 30 and (360 mA).
When LED current is changed, please use the power supply that has enough in current capacity from
setting current
(2) Emission pulse width (Bank0 Addr = 0x48, 0x49, 0x4A, 0x4B)
It needs to set same value both 0x48 and 0x4A in register.
Pulse width is about 0.25 μs per value 1.
Standard operation condition is typ.64μs.
It is possible to set up pulse width between 5 and 300 μs.
(3) Frame Rate (Bank1 Addr = 0x65, 0x66)
Please refer to the 1-3. register map for the calculation method of Frame Rate.
Standard operation condition is typ.120fps.
Please set up less than 240fps.
(4) IDLE S1 Time (Bank1 Addr = 0x67, 0x68)
IDLE S1 Time is the register for setting idle time under standby state1.
Frame rate of Standby state1 is set by IDLE S1 Time.
Please refer to 1-3 Register map with respect to calculation method.
Frame rate of Standby state1 is set to 60fps under standard operation condition.
(5) IDLE S2 Time (Bank1 Addr = 0x69, 0x6A)
IDLE S2 Time is the register for setting idle time under standby state2.
Frame rate of Standby state1 is set by IDLE S2 Time.
Please refer to 1-3 Register map with respect to calculation method.
Frame rate of Standby state2 is set to 30fps under standard operation condition.

(6) OP to S1 Time (Bank1 Addr = 0x6B, 0x6C)
When there is no object for certain time (below threshold of signal intensity), GP2Y8E01 is shift to standby
state1 from operation state in order to decrease power consumption. OP to S1 Time is the register of setting
time when there is no object. This is set to 10 seconds under standard operation condition. Please refer to
1-3. register map with respect to calculation method.
When object is detected under standby state1, it will shift to operation state. Please refer to 1-6. (5) State
Machine Diagram with respect to the detail of state shift in each state.
(7) S1 to S2 Time (Bank1 Addr = 0x6D, 0x6E)
When there is no object for certain time (below threshold of signal intensity), GP2Y8E01 is shift to standby
state2 from standby state1 in order to decrease power consumption. S1 to S2 Time is the register of setting
time when there is no object. This is set to 10 seconds under standard operation condition.
Please refer to 1-3. register map with respect to calculation method.
When object is detected under standby state2, it will shift to operation state. Please refer to 1-6. (5) State
Machine Diagram with respect to the detail of state shift in each state.

■Notes
[Advice for the optics]
● Lens of this device shall be kept cleanly. There are cases that the refractive material (for example, dust, water,
oil or so on) deteriorate the characteristics of this device. Please consider the mounting state or housing structure
in actual application according to the customer’s environment.
● 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 shall be recommended to use
over 90% transmittance at the emitting wavelength range of LED for this product (λ=950nm±70nm). Also,
as there are cases that the characteristics may not be satisfied with according to the distance between the
protection cover and this product, the thickness of the protection cover or the shape 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 in actual application sufficiently whether the characteristics of this
sensor do not change by the object, because there are cases that the characteristics may not be satisfied with.
● When the detector receive direct light from the sun, tungsten lamp and so on, there are cases of malfunction.
Please consider the design that the detector does not receive direct light from such light source. It has the
possibility to be able to avoid malfunction by means of register setting of decrease emission pulse width
and increase of LED current. Please confirm the operation in actual application sufficiently because there are
cases that the characteristic and ratings may not be satisfied with in case that register setting is changed.
● In case that there is the reflective object in the back of target object for coordinate measuring, there are cases of
malfunction due to the reflection by it. Please use this device after confirming sufficiently.
● Output distance data between the object and this product is relative distance data and it is possible to detect
the object approaching. Because of relative distance, output data is different by object size even if they are on
same distance. Please consider output data is relative distance in case of using distance output data.
[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.
● If external pressure is brought on this product, there are possible that the characteristic is defected by
changing position between case with lens and FPC, or FPC or chip capacitor is damaged. Please be careful.
