This slide shows a product map of ROHM’s photoreflectors. The vertical axis indicates the package area and the horizontal axis the detection distance. Products in mass production are shown in red and those under development or are planned are in blue. The RPR-220 is a mid-range analog type with built-in infrared LED and phototransistor, featuring a detection distance ranging from 5mm to 50mm. The RPR-0521RS is a mid-range digital type that integrates an infrared LED and photo IC, with a detection range of 5mm to 100mm. In the future, ROHM is considering a lineup that supports even longer wavelengths and distances.
