■ Precautions for Use
1. In order to stabilize power supply line, connect a by-pass capacitor of more than 0.33µF between VCC and GND near the device.
2. For cleaning
Acryle resin is used as the material of the lens surface. As to cleaning, this refractive type photointerrupter shall not clean by
cleaning materials absolutely. Dust and stain shall clean by air blow, or shall clean by soft cloth soaked in washing materials.
3. The connector should be plugged in / out at normal temperature.
4. As for other general precautions, refer to the chapter "Precautions for Use".
