Design Considerations
■
●
Design guide
1) Prevention of detection error
To prevent photointerrupter from faulty operation caused by external light, do not set the detecting face to
the external light.
2) Distance characteristic
Please refer to Fig.10 (Relative collector current vs. Distance) to set the distance of the photointerrupter
and the object.
This product is not designed against irradiation and incorporates non-coherent IRED.

Degradation
In general, the emission of the IRED used in photointerrupter will degrade over time.
In the case of long term operation, please take the general IRED degradation (50% degradation over 5
years) into the design consideration.
