Optical Sensors Product Line


ROHM offers a wide array of optical sensor products


ROHM Optical SensorsROHM offers a range of optical sensors and communication devices that consists of IR LEDs and phototransistors to fully integrated remote control receiver modules, IrDA transmitters, photointerrupters, and customized proximity sensor detectors.

IR LEDs and transistor sensor products are offered in packages ranging from standard T1, T11/4 packages to very small low profile (0.9 mm) SMD top view and side view packages, all featuring ambient light resistance with wide or narrow viewing angles. These devices are suitable for remote control transmitters, games, security, industrial applications, and proximity detection.

Integrated products such as photointerrupters and reflectors are offered in a variety of package sizes and different gap and slit widths. High accuracy detection due to double molding technology makes them ideal for printer applications, including paper/door detection and motor rotation/position sensing.

Tilt sensors offered in small, low profile, low noise SMD packages are applicable for orientation detection and image rotation in digital cameras, cell phones, tablet computers, and other handheld devices.

ROHM IR receivers and IrDA communication devices with integrated LSI / IR components operate at low voltage and low power consumption while internal filters and shielding contribute to low noise operation and greater EMI resistance.

IR LEDs and Emitters

IR Emitters ROHM’s SIM-030ST and SIM-040ST are high-performance IR LEDs ideally suited for proximity sensor applications. These surface-mount IR LEDs feature breakthrough IR wavelength technology providing peak output of 870 nm, compared to 950 nm for comparable devices. The 870 nm level is much closer to the peak wave sensitivity of phototransistors (sensors), thus achieving higher efficiency proximity sensing and energy savings of up to 66 percent. In addition, the small package footprint and low-profile further enhance their application in cell phones and other portable devices.

Tilt Sensors

Tilt SensorsThis is a surface-mount, optical type 4-directional sensor based on the new concept ”Optical” solution. This device receives less influence from vibration than the mechanical type device and is also free from magnetic influence unlike the magnetic type device -- so this device detects up/down in four directions accurately. RPI-1040 is an optical surface mount 4-way detection sensor with one IR LED and two phototransistors for detecting orientation, rotation, or fall in a variety of applications. Features include a thin package; silent, noise-free operation; shielded from vibration, magnetic and RF noise; and high precision detection. This tilt sensor is suitable for cell phone, digital camera, portable audio, iron, and heating fan applications.
