10. NOTES
10.1. Design restrictions/precautions
If used for outdoor applications, be sure to apply suitable supplementary optical filter, drip-proof and
anti-dew construction. This sensor is designed for indoor use.
In cases where secondary accidents due to operation failure or malfunctions can be anticipated, add a
fail safe function to the design.
10.2. Usage restrictions/precautions
To prevent sensor malfunctions, operational failure or any deterioration of its characteristics, do not
use this sensor in the following, or similar, conditions.
A.
B.
C.
D.
E.
F.
G.
In rapid environmental temperature changes
In strong shock or vibration.
In a place where there are obstructing materials(Glass, Fog, etc) through which infrared rays cannot
pass within detection area.
In fluid, corrosive gases and sea breeze.
Continual use in high humidity atmosphere.
Exposed to direct sun light or headlights of automobiles.
Exposed to direct wind from a heater or air conditioner.
10.3. Assembly restrictions/precautions
Soldering
A. Use soldering irons when soldering .
B. Avoid keeping pins of this sensor hot for a long time as excessive heat may cause deterioration of its
quality.(Ex. Within 5 sec. at 350 deg.C)
Washing
Be sure to wash out all flux after soldering as remainder may cause malfunctions.
Use a brush when washing . Washing with an ultrasonic cleaner may cause operational failure.
A.
B.
