Precautions

• When removing flux with chemicals after soldering, clean only the soldered part of the leads. Do not immerse the

entire package in the cleaning solvent. Chemical residue on the LED emitter or the photodetector inside the photo-IC

case may adversely affect the optical characteristics of the device and may drastically reduce the threshold input

current.

• The case is made of polybutylene-terephthalate. Oil or chemicals may cause the package to melt or crack. Care

should be taken regarding the environment in which the device is to be installed.

• Mount the device on a level surface.

• Output fluctuates for 100 μs after power-on while the internal circuit stabilizes.

• The threshold input current increases over time due to current flowing in the infrared LED. The design of circuits that

are to incorporate the device must take into account the change in threshold input current over time. The change in

threshold input current is equal to the reciprocal of the change in LED infrared optical output.

• Choose a high-quality shutter material that is impermeable to light. If the material is of inferior quality, light from the

LED may pass through the shutter, causing the device to malfunction.
