TCRT9000 Reflective Light Barrier Sensor 5mm (TCRT9000 Optical Sensor)
The TCRT9000 Reflective Light Barrier Sensor 5mm is an infrared based optical sensor designed for non contact object detection using reflected IR light. It integrates an infrared emitting diode and a phototransistor placed side by side in a single package. When an object comes within the sensing range, the emitted IR light is reflected back to the phototransistor, causing a change in output signal for detection.
The TCRT9000 sensor is widely used in India for embedded systems, industrial electronics, robotics, and automation applications. It is valued for its high resolution detection, fast response, and reliable performance in applications such as line tracking, object detection, and speed sensing.
