Vishay has created a fast opto-coupler that can operate at 25Mbit/s. Called VOIH72A, is has a digital buffering on the input and output. “The component combines a maximum pulse distortion of only 6ns, a maximum supply current of 2mA and a supply voltage range of 2.7 to 5.5V, and is fast enough to support bus systems such as SPI, as ...

Embedded World 2025: LED design is highlighted by Rutronik with its RAB5 adapter board. It features ams Osram Osire LEDs which are designed for dynamic, ambient lighting. LEDs are customisable to meet specific applications, using the manufacturer’s graphic user interface (GUI). LEDs are individually addressable chips for colour and driver selection. The LEDs can be used for interior and ambient ...

At Embedded World today, Samtec announced mid-board optical transceivers for embedded and rugged applications, including phased array radar and medical imaging. ‘Mid-board’ describes optical links that replace PCB tracks for very high speed signals. The new transceivers, branded Halo-C, are aimed at PAM4 modulated 56Gbit/s (112Gbit/s in development) per lane links with 16 channels (eight bidirectional). Read all the latest news from Embedded ...

How do you stop migrating birds from being attracted to oil rigs at night? The reasons that they should not land are two-fold: the mess that they make adds to maintenance costs, and birds that land are more likely to die before competing their journey. “Offshore platforms, such as oil and gas rigs, wind turbines, and their substations, offer a ...

Cree is aiming at horticulture lighting with a 660nm red led that is 6% more efficient than its XP-G3 Photo Red S Line devices. Called the XP-L Photo Red S Line, “this extra performance can be used to lower Photo Red LED count in luminaires by 35% while still maintaining the same total system efficiency”, according to the company. A typical ...

Toshiba Electronics has introduced a 60V 1A single-contact photo-relay in a 2.6 x 7mm 4pad SO4 package. Called TLP3640A, it can switch 60Vdc or 60Vac peak, with a typical on-resistance of 0.14Ω and maximum off-state leakage of 1µA. 100ms pulses of up to 3A can be carried. Operation is over -40 to +110°C, and de-rating starts at 25°C, dropping linearly ...

ElFys has launched circular four-quadrant near-infra-red detector with a 14mm diameter active area, leading to 38.5mm2 of sensing surface in each quarter. Named QPD-385-Y, the sensor’s dark current is typically 5nA per element (140V bias, 30nA max) with a temperature coefficient of 1.11x/°C. Illuminated with 1.064μm wavelength light, at the same 140V bias typical sensitivity is 640mA/W (500mA/W minimum). Capacitance ...

Augmented reality glasses need extremely micro-bright displays to compete with daylight, and if that is not a sufficient challenge for industry, power consumption and lifetime also need to be kept under control. Towards these triple goals, Fraunhofer Institute for Photonic Microsystems (IPMS) has developed a novel way to stack OLEDs “introducing a highly efficient monochrome OLED microdisplay with a brightness ...

Gaggione is offering versions of its Avika range of LED streetlight lenses made using recycled plastic. We are “incorporating recycled PMMA into our range, derived from recycled industrial scraps”, according to the company. “Our team selected one of the most transparent recycled materials on the market: recycled Plexiglas 8N. This material, both lightweight and durable, guarantees high performance in terms ...

Toshiba is aiming at 400V automotive systems with a 400V photo-relay that can handle 900V and ~30mA. Recommended maximum operating voltage is 720V. Called TLX9150M, it measures around 10 x 8 x 2.5mm and can carry 50mA at 25ºC, 20mA at 105ºC and 10mA at 125ºC, or 1ms pulses of 150, 60 and 30mA respectively. The package, SO12L-T has 8mm ...
