GP2S28 Reflective Photo Interrupter Sensor 6mm (GP2S28 Optical Sensor)
The GP2S28 Reflective Photo Interrupter Sensor 6mm is a compact infrared optical sensor designed for non contact object detection and position sensing. It integrates an infrared emitting diode and a phototransistor placed in the same direction, allowing detection based on reflected IR light. This reflective sensing method enables reliable detection without requiring objects to pass through a slot, making it suitable for compact designs.
The GP2S28 sensor is widely used in India for embedded systems, printers, automation equipment, and industrial electronics. It is valued for its stable output, fast response, and ease of integration in applications such as object detection, motion sensing, and position tracking.
