ROHM offers a wide array of optical sensor products |
|
 ROHM 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 Phototransistors-Sensors  SML-810TB features high gain and collector current. This molded type chip is ideal for reverse mounting. Other features include low profile, accurate positioning, and it saves board space. This sensor is ideally suited for SMD reflow assembly applications. SCM-014TB features high gain and collector current. This top-view molded chip is designed for automatic mounting and SMD reflow assemblies. Other features include high sensitivity, 800 nm peak wavelength, and outstanding ambient light filtering. This sensor is also ideal for photo sensing and motion sensing applications. RPM-012PB is an ultra-compact side-view chip sensor. It’s ideal for high sensitivity optical remote control applications when used in combination with the SIM-012SB emitter. Features include high power lens and ultra-compact surface mount package. Reflow is possible.
Photointerrupters  RPI-0128 is a double mold type photointerrupter in an ultra-miniature, surface mount package featuring a 1.2mm gap width and accurate 0.2 mm narrow beam detection. Other features include vertical slit and availability in DIP and SMD packages. This photointerrupter is ideal for digital cameras, digital video cameras, and mini industrial sensors. RPI-128 is a double mold type photointerrupter in an ultra-miniature through-hole package featuring a 1.2mm gap width and accurate 0.2 mm narrow beam detection. Other features include vertical slit and availability in DIP and SMD packages. This photointerrupter is ideal for digital cameras, digital video cameras, and mini industrial sensors.
Tilt Sensors  This 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.
