5mm IR Transmitter Receiver Pair

This pair includes a high-power directional IR LED and a filtered photodiode. The narrow beamwidth IR LED emits focused infrared light, while the photodiode filters out ambient light without external circuitry. With proper circuit design, it can achieve reflective sensing up to 200 mm and is suitable for high-speed applications like encoders.
