Mouser Electronics Begins Distribution of ROHM Semiconductor's RPR-0730 Photo Reflector

As an industry leader in New Product Introduction (NPI), Mouser Electronics, headquartered in Mansfield, Texas, USA, has begun distributing the new photo reflector "RPR-0730" from ROHM Co., Ltd., headquartered in Ukyo-ku, Kyoto. This product is an analog optical sensor capable of high-precision detection of high-speed moving objects in consumer and industrial equipment. The "RPR-0730" handled by Mouser adopts a unique 940nm infrared IrVCSEL as its light source and combines it with ROHM's high-speed phototransistor as the light-receiving element, making it an ultra-compact optical proximity sensor. This configuration achieves excellent directivity and low power consumption compared to conventional LED-based solutions. It also enables high-speed and high-precision detection, making it suitable for applications that were difficult with conventional digital output types, such as print detection in multifunction printers and label printers, and rotation detection of motors and gears. Furthermore, by adopting an analog output phototransistor as the light-receiving element, it achieves a response time of 10μs, enabling accurate identification of fine lines as narrow as 0.1mm, outperforming conventional LED light sources. The "RPR-0730" comes in an ultra-compact (2.0 × 1.0 × 0.55 mm³) package.
