Precautions
The following points must be borne in mind.
1. Soldering temperature: 260擄C max
Soldering time: 5s max
(Soldering must be performed 1.5mm under the package body.)
2. Clean only the soldered part of the leads. Do not immerse the entire package in the cleaning solvent.
3. Mount the device on a level surface.
4. Screws should be tightened to a clamping torque of 0.59 N錕?frac12;錕絤.
5. The package is made of polycarbonate. Polycarbonate is usually stable with acid, alcohol and aliphatic
hydrocarbons, however, with petrochemicals (such as benzene, toluene and acetone), alkalis, aromatic
hydrocarbons, or chloric hydrocarbons, polycarbonate may crack, swell or melt.
Please take this into account when choosing a packaging material by referring to the table below.

Conversion efficiency falls over time due to current which flows in the infrared LED.
When designing a circuit, take into account this change in conversion efficiency over time.
The ratio of fluctuation in conversion efficiency to fluctuation in infrared LED optical output is 1 : 1.
