Compact optical switch for non-contact switching applications Everlight’s reflective type opto interrupter ITR1201 integrates an infrared emitter and a silicon phototransistor in a plastic double moulding housing Everlight Electronics’ reflective type opto interrupter ITR1201SR10A/TR, in its ITR series of reflective sensors, is for use in printers, copiers, scanners and for non-contact switching environments such as use as a proximity sensor. It is a light reflection switch which includes a GaAs IR-LED and an NPN phototransistor with a highly photosensitive receiver for short distances, operating in the infrared range. Other key features are a fast response time, a very stable collector current, a cut-off visible wavelength of below 700 nm and an improved MSL (moisture sensitivity level) from level 4 to 3. The double moulding manufacturing process employed, compared to the traditional glue dispense manufacturing process results in a smoother surface which not only enhances the look but also raises the reliability. The ITR1201 has a flat profile of only 1.5 mm Everlight www.everlight.com 13 Mpixel CMOS image sensor cuts power for 120 fps HD video T4KB3 is a 13-megapixel backside illumination (BSI) CMOS image sensor with an optical format of 1/3.07 inch. Offering video capture at up to 120 fps with full 1080p HD, the image sensor is suited for use in high end smartphones and tablets. With demand growing for small form factor chips, destined for ever slimmer mobile devices, the T4KB3 makes use of proprietary Toshiba design techniques to deliver a device claimed as the smallest 13 megapixel sensor. Low power circuitry has reduced power consumption, to 53% of that used by the preceding T4K82 image sensor, and the new chip achieves 200 mW, or less, at 30fps, with full 13 megapixel output. Image brightness is boosted four fold by using Bright Mode technology and the T4KB3 offers full 1080p HD video capture at 120 fps. The sensor is fitted with 8 kbit of One Time Programmable (OTP) memory and lens shading correction data for two conditions can be stored. This permits different correction data for indoor or outdoor use. The T4KB3 measures 8.5 x 8.5 mm, with auto focus, and 6.7x6.7mm with a static focus. Toshiba Electronics Europe www.toshiba.semicon-storage.com Modular ceiling LED light consumes less than 15-W GlacialLight has introduced the second generation of the company’s modular ceiling light series for indoor commercial lighting – GL-PL0303-V2 and GL-PL0312-V2. Using a new generation of LED thermal and lighting technology the 295 mm square GL-PL0303- V2 consumes 14.8 W while producing up to 1260 lumens, and the longer GL-PL0312- V2 fluorescent tube replacement LED light, with dimensions of 295 mm x 1195 mm, reduces energy consumption to 44.5 W while producing up to 3900 lumens. At 295 mm, the LED ceiling light fit within the width of standard modular ceiling tiles without consuming too much energy. The 295 mm square GLPL0303 V2 produces a bright yet non-obtrusive 1100 lumens or more and the 295 mm x 1195 mm GL-PL0312-V2 produces 3600 lumens or more, meaning less luminaires to install, and lower energy bills for the same amount of light. Compared to fluorescent tube lighting, the LED panel lights from Glacial- Light claim to produce a smooth, bright light across the entire LED panel, creating more pleasant and even area illumination with less flicker and glare. Color temperatures can be chosen from 3000K (warm white), 4000K (neutral white), or 6000K (cool white) to suit the lighting ambience. A dimming option with 1-10 V DC, PWM and Resistor dimming is compatible with a variety of lighting control systems and switches, allowing users to easily adjust the level of light. The included LED driver has a two-stage design and is IP67 and CUL certified. In two different sizes - a square 295 mm model as well as a longer 295 mm x 1195 mm model the lights with an ultra-slim 10 mm thickness fit within standard suspended ceilings. The lights can be recessed mounted (295 mm standard, 300 mm with the spacer or 315 mm with the clip-on mounts). GlacialLight www.glaciallight.com Forza, NHK show 133-Mpixel sensor Forza Silicon Corp., in collaboration with researchers at Japanese broadcaster NHK have presented a CMOS image sensor with resolution of 133-megapixels and able to capture video at 60 frames per second. The chip is intended for an 8K-resolution single-chip camera. The sensor was presented at the International Solid-State Circuits Conference (ISSCC) held in San Francisco in February. The sensor was designed by Forza (Pasadena, Calif.) and fabricated for NHK using a 0.18-micron 3.3V/1.8V manufacturing process with 1D stitching together multiple mask images on a die. To date conventional image sensors for 8K applications have used 8 MP and 33 MP solutions in large optical formats. These sensor solutions have not been effective in managing the trade-offs between size and resolution. In order to eliminate the bulky lens/colorprism optical system of previous generation cameras, the team developed a single-chip 133 MP image sensor. The sensor takes advantage of Forza Silicon’s third generation readout architecture to achieve frame frequency of 60 fps. The Gen 3 readout architecture uses a pseudo-column parallel design with redundant 14-bit successive approximation register ADCs to achieve a throughput of 128Gbit/s at full resolution and frame rate. “Forza’s dedicated support and its image sensor design expertise enabled us to achieve the Super Hi-Vision 8K singlechip camera — the largest pixel count of any video image sensor,” said Hiroshi Shimamoto, senior research engineer at NHK Science & Technology Research Laboratories (STRL).
