The RPR-220 Optical Sensor is a compact reflective infrared sensor designed for reliable object detection, position sensing and motion feedback in electronic and automation projects. Supplied as a through-hole device, it is ideal for PCB mounting in prototyping, robotics, and embedded control systems.
This integrated reflective sensor contains both an infrared LED emitter and a phototransistor detector housed within a single package. When an object passes in front of the sensor, reflected infrared light is detected by the phototransistor, allowing the circuit to determine the presence, position, or movement of an object.
The RPR-220 is widely used in line-following robots, rotary encoders, position detection systems, counters, and automated equipment, providing dependable sensing performance in a compact footprint. Fully stocked in the UK, it is available for fast dispatch for both hobby and professional applications.
