    CNY70 Reflective Optical Sensor with Transistor Output

    RBD-3931

    The CNY70 Reflective Optical Sensor by Vishay Telefunken integrates an infrared emitter and phototransistor in a compact, black plastic housing. The emitter and detector are positioned side-by-side, enabling it to detect objects by sensing infrared light reflected from nearby surfaces. It is a widely used sensor for line tracking, object detection, and rotary encoder applications.
