Precautions

• When you consider a combined use with an LED, be sure to use an infrared LED. Visible rays in wavelength of

less than 700 nm cannot be detected.

• Make sure the shielding plate that is used to detect positions is manufactured from materials with superior

light-shielding characteristics. Insufficient shield can cause malfunction.

• Photo ICs contain a high-sensitivity amplifier. Toshiba recommends connecting a capacitor of about 0.01 μF that

• Please install so that disturbance light is not irradiated by these products.

When disturbance light (incandescence light etc.) 700 nm or more is detected, it may incorrect-operate. Please

perform sufficient evaluation and verification by set.
