What is a Photointerrupter?

High Photoelectric Conversion Power-Saving Interrupters

By bringing the receiving sensitivity characteristics of the phototransistor close to the IrLED emission wavelength, a power-saving photointerrupter that eliminates the wavelength difference loss component is achieved.
