The photointerrupter is also called a transmissive photoelectric sensor, photointerrupter, photointerrupter, photointerrupter, that is, the light-emitting component and the light-receiving component are arranged face-to-face and arranged in the same package. When the detection object passes through The principle of shading can realize the detection function. ROHM refers to this type of penetrating photoelectric sensor as an interrupter. The light-emitting component uses GaAs infrared light-emitting diodes with high output power and long service life, while the light-receiving component mainly uses a single phototransistor or a special IC.
The photo-interrupter module and digital interface, built-in 13 LEDs to build a simple circuit to produce. Illumination interrupter warning light. It is equipped with an LED digital interface, and the photoresist is connected to 3 sensor interfaces. When the light interrupter senses the device detects the key signal, the LED light is on, otherwise it turns off.
