Performance
■
Using the transmitter shown in Fig. 1, the output signal of the light detecting unit is good enough to meet the following items in the standard optical system in Fig. 2.
(1) Linear reception distance characteristics
When L=0.2 to 5 m, Ee < 10 lx ( *4) and φ =0˚ in Fig. 2, the output signal shall meet the electrical characteristics in the attached list.
(2) Sensitivity angle reception distance characteristics
When L=0.2 to 3 m, Ee < 10 lx ( *4) and φ<= 30˚ in the direction X and θ =0˚ in the direction Y in Fig. 2,
the output signal shall meet the electrical characteristics in the attached list. Further, the electrical characteristics shall be met
when L=0.2 to 5 m, Ee < 10 lx (*4) and φ =0˚in the direction X and θ<= 15˚ in the direction Y.
*4 It refers to detector face illuminance.

Precautions for Operation
(1) Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of
light emitting device and the characteristics of the light detecting unit.
(2) Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse.
Care must be taken not to touch the light detector surface.
• Conduct cleaning as follows.
(3) Cleaning
Solvent dip cleaning : Solvent temperature of 45 ˚C max., dipping time : Within 3 minutes
Ultrasonic cleaning : Elements are affected differently depending on the size of cleaning bath, ultrasonic output, time,
• Use the following solvents only.
Solvents : Ethyl alcohol, methyl alcohol or isopropyl alcohol
To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
(4)
(5) Do not apply unnecessary force to the terminal.
(6) Example of recommended external circuit (mount outer mounting parts near the sensor as much as possible.)
Wavelength λ (nm)
size of PWB and mounting method of elements.
Conduct trial cleaning on actual operating conditions in advance to make sure that no problem results.
