Infrared LEDs & Optical Sensors

ROHM Semiconductor Infrared LEDs and Optical Sensors include a range of optical sensors and communication devices, from IR LEDs to phototransistors and photointerrupters. ROHM Semiconductor IR LEDs and transistor sensor products are offered in packages ranging from standard T1/T1 1/4 packages to very small low profile (0.9mm) SMD top view and side view packages, all featuring ambient light resistance with wide or narrow viewing angles. These optical sensor devices are suitable for remote control transmitters, games, security, industrial applications, and proximity detection.
