CNY70 Reflective Optical Sensor with Transistor Output (CNY70 IR Sensor)
The CNY70 Reflective Optical Sensor is an infrared based sensor designed for non contact detection using reflected IR light. It integrates an infrared emitting diode and a phototransistor in a single compact package, both facing the same direction to detect reflected light from nearby objects.
This sensor is optimized for short range detection and is widely used in applications like line following, position sensing, and encoder systems due to its high sensitivity and compact design.
