RPR-220 is a photoresistor with high sensitivity, small size and light weight. It is mainly used in compact disc players, copiers, game machines and other office automation equipment.
The RPR-220 is a through‑hole reflective photosensor (photoreflector) designed for high‑sensitivity detection of visible light. It includes a built‑in visible‑light filter to reduce stray‑light influence and is suitable for a wide range of electronic equipment such as audio‑visual devices, office automation, and consumer electronics.
Key specifications include a forward current of 50 mA, reverse voltage of 5 V, power dissipation of 80 mW, and an operating temperature range of –25 °C to +85 °C. The device offers a peak sensitivity at 800 nm and a fast response time of 10 µs, making it ideal for applications requiring precise distance measurement and light detection.
