Reflective Type Photosensors

The RPR-0730 is an ultra-compact optical proximity sensor (photoreflector) that integrates a proprietary 940nm VCSEL as the light-emitting element -offering superior directionality and lower power consumption than conventional LEDs –along with ROHM’s high-speed phototransistor as the light-receiving element. This combination enables faster, more precise detection, making it ideal for demanding applications such as print detection in multifunction and label printers as well as rotation sensing in motors and gears -areas where conventional digital output types often fall short.

RPR-0720 is an ultra-compact optical proximity sensor that adopts an in-house IR VCSEL which is more power-efficient than LEDs and features excellent directivity as the light emitting element and a digital output optical sensor IC for the light receiving element. This makes it ideal for wearables and other small electronic devices requiring attachment/detachment detection.
