Mouser Begins Stocking ROHM Semiconductor Photoreflector “RPR-0730”

As an industry leader in New Product Introduction (NPI), Mouser Electronics (Headquarters: Mansfield, Texas, USA), which drives innovation, has begun stocking ROHM Co., Ltd.'s (Headquarters: Ukyo-ku, Kyoto, Japan) new photoreflector “RPR-0730”. This product is an analog optical sensor that can precisely detect fast-moving objects in consumer and industrial equipment.

The “RPR-0730” handled by Mouser is an ultra-compact optical proximity sensor that adopts a unique 940nm infrared IrVCSEL as its light source and combines it with ROHM's high-speed phototransistor as the light-receiving element. 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 in motors and gears. Furthermore, by adopting an analog output phototransistor as the light-receiving element, it achieves a response time of 10μs and can accurately identify fine lines as narrow as 0.1mm, demonstrating performance superior to conventional LED light sources.

The “RPR-0730” is an ultra-compact (2.0 × 1.0 × 0.55 mm³) package.
