The RPI-352C40C is a reflective photosensor manufactured by Rohm Semiconductor. This compact sensor integrates an infrared LED and a phototransistor into a single package, enabling it to detect the presence or absence of an object by measuring the amount of infrared light reflected back to the sensor. It's commonly used in applications requiring non-contact object detection.
